Analytical cookies are used to understand how visitors interact with the website. A modification of the extractions previously discussed in this chapter is to perform a chemical reaction in the separatory funnel in order to change the polarity and therefore partitioning of a compound in the aqueous and organic layers. Clostridium fermentation has two successive stages: the acidogenic stage (acid generation) and solventogenic stage (solvent generation). The acid-base extraction is possible because the acid will react with a base to form a water-soluble salt. Isolation and Purification of Cinnamic Acid The aqueous layer containing the ionic compound sodium cinnamate is acidified with concentrated HCl. If fine crystals form (which are quite common), they will clog the filter paper and interfere with adequate drainage. The hydroxide, these electrons here, would deprotonate the phenol, giving you again the phenolate anion, along with the hexane in your organic layer. After acidification, two routs may be taken, depending on if the acidic component is solid or liquid. Obtain a separatory funnel (Figure 4.23a). A glass stirring rod can be used to knock down stubborn clinging droplets. The interface between the layers should settle rather quickly, often within 10 seconds or so. 0000003227 00000 n Dispense and use chromic acid solution in hood. Drain the majority of the bottom layer into an Erlenmeyer flask. 56 0 obj The purity of the n-butyric acid obtained in hexane is 98%. You would dissolve the mixture in an organic solvent and then perform as many extractions as are necessary with an NaHCO3 aqueous solution in order to extract the butyric acid. Sodium bicarbonate is preferable to \(\ce{NaOH}\) in this process, as it is a much weaker base; washing with \(\ce{NaOH}\) could cause hydrolysis of the ester product. Add about 10 mL of dichloromethane 2. - 1 stationary, 1 moving. As previously discussed, carboxylic acids can be extracted from an organic layer into an aqueous layer by shaking them with basic solutions, which converts them into their more water-soluble salts.

In this manner, a mixture of benzoic acid and cyclohexane can be separated (Figure 4.54b). The PEG was precipitated with an iodine solution and filtered. How would you separate a mixture of p toluic acid and p toluidine dissolved in ether? please explain how to draw a flowchart to show that separate a mixture of butyric acid and hexane.the example in the linkChemistryScienceOrganic chemistry CH 128. Repeat the extraction a third time by adding the aqueous layer from the second extraction into the separatory funnel, followed by another. As was discussed in the previous section, \(\ce{NaOH}\) can be used to convert a carboxylic acid into its more water-soluble ionic carboxylate form. The solubility properties of carboxylic acids are substantially different than their corresponding carboxylate salts. For example, imagine that a mixture of benzoic acid and cyclohexane is dissolved in an organic solvent like ethyl acetate in a separatory funnel. The invention relates to non-woven protein fibers and to methods for forming and producing the same. To clean a separatory funnel, first rinse it with acetone into a waste container. Extracting Carboxylic Acids vs. Phenols. Due to its acidic nature, benzoic acid can undergo a reaction with \(\ce{NaOH}\) as follows, resulting in the carboxylate salt sodium benzoate. What does it mean that the Bible was divinely inspired? Alternatively, it may possibly be . It is a carboxylic acid having the structural formula CH3CH2CH2CO2H. %%EOF The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. \[\begin{array}{ccccccccc} \ce{PhCO_2H} \left( aq \right) & + & \ce{NaOH} \left( aq \right) & \rightarrow & \ce{H_2O} \left( l \right) & + & \ce{PhCO_2Na} \left( aq \right) & & \left( \text{or } \ce{PhCO_2^-} \ce{Na^+} \right) \\ \text{Carboxylic acid} & & & & & & \text{Carboxylate salt} & & \end{array}\]. { "4.01:_Prelude_to_Extraction" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.02:_Overview_of_Extraction" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.03:_Uses_of_Extraction" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.04:_Which_Layer_is_Which" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.05:_Extraction_Theory" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.06:_Step-by-Step_Procedures_For_Extractions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.07:_Reaction_Work-Ups" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.08:_Acid-Base_Extraction" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { "00:_Front_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "01:_General_Techniques" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "02:_Chromatography" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "03:_Crystallization" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "04:_Extraction" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "05:_Distillation" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "06:_Miscellaneous_Techniques" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "07:_Technique_Summaries" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "08:_About_the_Author_-_Lisa_Nichols" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "zz:_Back_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, [ "article:topic", "Liquid-Liquid Extraction", "authorname:nicholsl", "Acid-Base Extraction", "showtoc:no", "license:ccbyncnd", "transcluded:yes", "source[1]-chem-93535", "source@https://organiclabtechniques.weebly.com/" ], https://chem.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fchem.libretexts.org%2FCourses%2FSUNY_Oneonta%2FChem_221%253A_Organic_Chemistry_I_(Bennett)%2F2%253ALab_Textbook_(Nichols)%2F04%253A_Extraction%2F4.08%253A_Acid-Base_Extraction, \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}\) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\)\(\newcommand{\AA}{\unicode[.8,0]{x212B}}\), Extracting Acid, Base, and Neutral Compounds, source@https://organiclabtechniques.weebly.com/, status page at https://status.libretexts.org. Draw a flowchart to show how you separate a mixture of butyric acid and hexane. A TLC plate of the reaction mixture at 1 hour of reflux showed residual unreacted carboxylic acid (Figure 4.56c), which is not uncommon due to the energetics of the reaction. This strategy can be extended to other examples. Mix the Solutions (for single extraction) Place the stopper on the funnel, and hold the funnel such that the fingers of one hand securely cover the stopper, while the other hand grips the bottom of the funnel (Figure 4.26a). 1. Instead use the first mixing method described. As a general rule of thumb, use one-third as much solvent for the extractions as the original layer (e.g. After filtration, the broth was added into PEG at different concentrations to form the aqueous two-phase solution. If the separatory funnel has a Teflon stopcock, reassemble the stopcock if it was taken apart to dry, placing the parts in the appropriate order (Figure 4.23b). The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. It's also the favored source of fuel for the cells lining the interior of the large intestine or colon. How would you separate butyric acid and hexane? In this section are described differences between general extraction procedures and the process as summarized in Figure 4.59. Hydrochloric acid is generally used to protonate amines. And now we've learned how to do extractions. You will use 2-mL portions of ethyl alcohol, isopropyl alcohol, and t -butyl alcohol in separate test tubes.

Separation of Butyric Acid and Hexane OH butyric hexane acid 1. Theory and Background: Distillation refers to the laboratory technique used to separate mixtures by heating them until evaporation, and then condensing said . What are some examples of how providers can receive incentives? Want to see the full answer? Acid-Base Extraction: Acid-base extraction is a technique that is widely used to separate organic compounds. This separation was performed using a liquid-liquid extraction. If liquid did drain from the funnel without replacement by an equal volume of air, a negative pressure would form in the funnel. If the bottom layer is the desired layer, and another extraction is to be done, add fresh organic solvent to the top layer still in the conical vial and repeat the extraction and separation. Sodium bicarbonate is preferable to \(\ce{NaOH}\) in this process, as it is a much weaker base; washing with \(\ce{NaOH}\) could cause hydrolysis of the ester product. A similar reaction occurs with phenols \(\left( \ce{PhOH} \right)\), and they too can be extracted into an aqueous \(\ce{NaOH}\) layer (Figure 4.58a). Chromatography. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. One is to hold the separatory funnel up to the light, or to shine a flashlight onto the glass (Figure 4.32b). To isolate, wash with brine (\(\times 1\)) if using diethyl ether or ethyl acetate, dry with a drying agent, and remove the solvent via rotary evaporator to leave the pure neutral component. Find the formal concentration of butanoic acid in each phase when 100.0 mL of 0.10 M aqueous butanoic acid is extracted with 25.0 mL of benzene at a pH of 4.00. Extracting Bases. Remove the stopper (it won't drain otherwise). Pour the contents to be extracted into a conical vial, or a glass tube with a tapered end (e.g. 1000 kg/hr of a feed containing 30 wt% acetone . 0000007038 00000 n Your eye can sometimes pick up on subtle differences in the way the liquids flow. This page titled 4.8: Acid-Base Extraction is shared under a CC BY-NC-ND 4.0 license and was authored, remixed, and/or curated by Lisa Nichols via source content that was edited to the style and standards of the LibreTexts platform; a detailed edit history is available upon request. acetic and butyric acids) as intermediate products prior to the formation of solvents like acetone, butanol and ethanol. When shaking an acidic solution with sodium bicarbonate in a separatory funnel, care should be taken to swirl gently and vent more frequently to release pressure from the gas. After allowing the layers to separate in the funnel, drain the bottom organic layer into a clean Erlenmeyer flask (and label the flask, e.g. Solubility of butyric acid in water = X g/ml . Also obtain a stopper (Teflon or ground glass) that fits well in the top joint of the funnel (Figure 4.23a). Paste your instructions in the instructions box. Title . Joined: Sat May 29, 2010 4:42 am. Calculation of formal concentration: Calculations of formal concentration ordinarily resemble the molar concentrations only that they are determined as the moles present in one liter of . Allow the layers to separate inside the pipette (Figure 4.37c), then delicately expel the bottom layer from the pipette into the container. The composition of the mixture is the same in the liquid and gas phases so both components boil at the same time, not separating. Show transcribed image text. Separate the layers with a Pasteur pipette. Allow the solution to sit for a period of time (even until the next lab period) if possible. 0000057667 00000 n How will you separate cinnamic acid and naphthalene? diethyl ether), as the volume often decreases dramatically after mixing. After partition of the solution, PEG and most butyric acid, acetic acid and butanol were contained in the PEG-rich phase. And carrier flow rate is an important consideration in selecting purge off time.). Hold the separatory funnel so that your fingers firmly cover the stopper. Perform a single extraction using approximately \(25 \: \text{mL}\) of diethyl ether (an exact amount is not necessary), as described previously, making sure to appropriately label each layer (e.g. The chemical formula for butanoic acid is CH3CH2CH2COOH. It may be difficult to remove the very last drop of bottom layer from the point of the vial. An acidic solute, HA, has a K a of \(1.00 \times 10^{-5}\) and a K D between water and hexane of 3.00. The neutral component will be the "leftover" compound in the organic layer. However, if the mixture contains a desired compound that can react with \(\ce{NaOH}\), a milder base such as sodium bicarbonate should be used. Therefore, a wash with \(\ce{NaOH}\) would convert benzoic acid into its ionic carboxylate form, which would then be more soluble in the aqueous layer, allowing for the sodium benzoate to be extracted into the aqueous layer. In certain embodiments, the invention provides a method of processing a protein comprising dissolving a protein in a solution, optionally removing any insoluble materials from the solution, and spraying the solution under an applied pressure. Don't throw away either layer until you are sure you've accomplished the goal of the extraction. Lower concentrations of \(\ce{HCl} \left( aq \right)\) are less hazardous, but increasing the volume of the aqueous layer by a large amount would affect the efficiency of subsequent extractions and filtering steps. As previously discussed, carboxylic acids can be extracted from an organic layer into an aqueous layer by shaking them with basic solutions, which converts them into their more water-soluble salts. Separate ester from carboxylic acid by using chromatography can be achieved by SiO2 gel column chromatography using ethyl acetate as a solvent. H bonding most significant; of low molecular mass. A second method is to carefully observe the layers while tilting the funnel back and forth to the side (Figure 4.32c). 0000005898 00000 n To separate the components, a water wash may be attempted to remove benzoic acid, but benzoic acid is not particularly water-soluble due to its nonpolar aromatic ring, and only small amounts would be extracted into the aqueous layer (Figure 4.54a). Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. For small volumes, use a centrifuge if one is available. by leo1352 Tue Jun 22, 2010 9:20 am. Question. leo1352 Posts: 38 Joined: Sat May 29, 2010 4:42 am. Q: Draw a flowchart to show how you separate a mixture of butyric acid and hexane. Therefore, it will not dissolve in sodium bicarbonate solution and does not release carbon dioxide. Ethanol and butyric acid react to form ethyl butyrate with the elimination of water: EtOH + HBut ---> EtBut + H20 but as the reaction in the laboratory would be carried out in the presence of hot sulfuric acid (sucks up the water thus pushing the reaction to the right) I have some doubts as to how fast it would take place in cold beer, if at all, unless some enzyme catalyzes it. \[\begin{array}{ccccccc} \ce{PhNH_2} \left( aq \right) & + & \ce{HCl} \left( aq \right) & \rightarrow & \ce{PhNH_3Cl} \left( aq \right) & & \left( \text{or } \ce{PhNH_3^+} \ce{Cl^-} \right) \\ \text{Basic amine} & & & & \text{Ammonium salt} & & \end{array}\]. These acids are also produced by the action of skin bacteria on human sebum (skin oils), which accounts for the odor of poorly ventilated locker rooms. A separatory funnel would be impractical when working with such small quantities, and conical vials (Figure 4.35) or centrifuge tubes are typically used instead. The compound phenol is considered as a weak acid. It is a colorless and oily liquid that is soluble in ethanol, water, and ether. Who are the experts? Cyclohexane would remain in the organic layer as it has no affinity for the aqueous phase, nor can react with \(\ce{NaOH}\) in any way. Usually, the mixture is dissolved in a suitable solvent such as dichloromethane or diethyl ether (ether), and poured into a separating funnel. If no solid forms upon acidification (or if fine crystals or low quantity of solid forms), extract the acidic component back into an organic solvent (\(\times 3\)). Basic compounds such as amines can be extracted from organic solutions by shaking them with acidic solutions to convert them into more water-soluble salts. Also, be sure to never throw away a layer until you are absolutely sure that you've done everything correctly. deprotonated. A modification of the extractions previously discussed in this chapter is to perform a chemical reaction in the separatory funnel in order to change the polarity and therefore partitioning of a compound in the aqueous and organic layers. The aqueous two-phase system was used to separate . Answer: A mixture of benzoic acid and benzophenone can be separated by using a base. Solution "top organic layer" and "bottom aqueous layer"). Periodically "vent" the funnel (open the stopcock while inverted to release pressure). If you had a mixture of butyric acid and hexane, how would you separate the two compounds?. Never point the tip at someone while venting. All rights reserved. The mixture is cooled and subsequent portions of 1 ml of hexane and 2 ml of water added, vortex-mixed for 15 seconds, placed in a centrifuge, allowed to reach a speed of 3000 rpm, and then stopped immediately. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. A minor film is not something to worry about because if a small amount does make it into the organic layer, a subsequent drying and filtration step will often remove it. Is then recovered in the organic phase 21.7 gl of n-butyric acid which corresponds, taking into account the dilution brought by the solvent: aqueous phase ratio, to an extraction yield of 87.5% and 0 , 52 g.1 acetic acid, a yield of 28%. The solution is tested with litmus paper to confirm its acidity. The acid is of considerable commercial importance as a raw material in the . If a solid forms upon acidification of the ionic salt, it can be collected through suction filtration. Isolation of a substance from animal or plant matter is another application of extraction, either to obtaining the compound for some end use (e.g . 0000002585 00000 n In this section are stepwise instructions on how to extract an aqueous solution with an organic solvent that is less dense than water (the organic layer will be on the top). In a base acid becomes soluble and other become insoluble. It does not store any personal data. It's also found in lower amounts in some foods. Legal. After acidification, two routs may be taken, depending on if the acidic component is solid or liquid.

But opting out of some of these cookies may affect your browsing experience. If you had a mixture of butyric acid and hexane, how would you separate the two compounds? Butyric acid is a fatty acid that's created when bacteria in your gut break down dietary fiber. 0000057458 00000 n Transcribed Image Text: Draw a flowchart to show how you separate a mixture of butyric acid and hexane. On occasion the compounds in a separatory funnel are so dark that they obscure the interface between the two layers. Drain the bottom organic layer into the flask used previously, where there should be roughly \(75 \: \text{mL}\) of dichloromethane from the three extractions. leo1352 Posts: 38 . Butyric acid, which is known under the systematic name butanoic acid. Experts are tested by Chegg as specialists in their subject area.

Bottles 1# and 6# experienced typically butyric acid-type fermentation, with total acetic and butyric acid reaching 78%, 75%, and pH value 4.70, 4.77 (Fig. The filtrate was subsequently distilled to separate butyric acid, where at the optimal conditions a yield as high as 91.74% 0.46% was demonstrated. Butanoic acid is a type of short-chain saturated fatty acid mainly found in vegetable oils . flowchart. You will use a chemically active extraction to convert the water insoluble benzoic acid into its water soluble salt by treating the carboxylic acid with base. sol. View Seperation Of Butyric Acid And Hexane.pdf from SCIENCE 2381 at Glebe Collegiate Institute. Mahdi. Basic compounds such as amines can be extracted from organic solutions by shaking them with acidic solutions to convert them into more water-soluble salts. The benzoic acid is also a strong acid, therefore it will dissolve in sodium bicarbonate solution to form salt and water by liberating carbon dioxide.. Butyric acid is an oily and colorless liquid. In this way, they can be extracted from an organic layer into an aqueous layer. Manual mixing is not recommended when using low-boiling solvents (e.g. Before pouring anything into a separatory funnel, be sure that the stopcock is in the "closed" position, where the stopcock is horizontal (Figure 4.24a). If you had a mixture of butyric acid and hexane, how would you separate the two compounds? I have done the butylation of fatt acids, the good news is the butyric acid is eluting at 7.2 min with a 60m DB-225 colum. Why do you wash the dichloromethane solution of your reductive amination product with sodium bicarbonate, rather than dilute aqueous HCl? Drain the bottom aqueous layer into an Erlenmeyer flask: it is acceptable to use the same flask that was used for the aqueous layer in the first extraction (that may have been labeled "bottom aqueous layer"). The Butyric acid will react with NaOH to produce sodium butyrate which will move to the aqueous phases where it will be more soluble. Have you tried n-butanol esterification (catalyzed with either sulfuric acid or BF3) ? "bottom aqueous layer"). One method is to add \(\ce{NaCl}\) or \(\ce{NH_4Cl}\) to the separatory funnel, which dissolves in the aqueous layer and decreases the ability of organic compounds to dissolve in water ("salting out"). 0000067199 00000 n Organic Chemistry Lab Techniques (Nichols), { "4.01:_Prelude_to_Extraction" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.02:_Overview_of_Extraction" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.03:_Uses_of_Extraction" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.04:_Which_Layer_is_Which" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.05:_Extraction_Theory" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.06:_Step-by-Step_Procedures_For_Extractions" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.07:_Reaction_Work-Ups" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "4.08:_Acid-Base_Extraction" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { "00:_Front_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "01:_General_Techniques" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "02:_Chromatography" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "03:_Crystallization" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "04:_Extraction" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "05:_Distillation" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "06:_Miscellaneous_Techniques" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "07:_Technique_Summaries" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "zz:_Back_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, [ "article:topic", "Liquid-Liquid Extraction", "authorname:nicholsl", "Acid-Base Extraction", "showtoc:no", "license:ccbyncnd", "licenseversion:40", "source@https://organiclabtechniques.weebly.com/" ], https://chem.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fchem.libretexts.org%2FBookshelves%2FOrganic_Chemistry%2FOrganic_Chemistry_Lab_Techniques_(Nichols)%2F04%253A_Extraction%2F4.08%253A_Acid-Base_Extraction, \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}\) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\)\(\newcommand{\AA}{\unicode[.8,0]{x212B}}\), Extracting Acid, Base, and Neutral Compounds, source@https://organiclabtechniques.weebly.com/, status page at https://status.libretexts.org.
