A three-component mixture of organic compounds in diethyl ether consists of a carboxylic acid, an amine base, and a neutral compound. After treatment with 3 M HCl and thorough mixing, what compound(s) will be present as major components of the aqueous phase? a)the neutral compound b)the carboxylic acid and the neutral compound c)the amine d)the amine hydrochloride salt

You weight out exactly 1.00 mg of benzoic acid and dissolve it in a mixture of 2.0 mL of diethyl ether and 2.0 mL of water. After mixing and allowing the layers to separate, the ether layer is removed, dried, and concentrated to yield 0.68 mg of benzoic acid. What is the Kp value (ether/water) for this system?

A student has a mixture of butanoic acid (liquid) and phenol ( ) (solid). The mixture is almost (1:1). The pas for both compounds are 4 -5 and 10 respectively. Both compounds are soluble in ether (organic solvent that is insoluble in water). Select the best technique to separate and recover each compounds. Recrystallization. Use strong basic water as a solvent and recover the solid while leaving the liquid behind. Add acid to recover the butanoic acid. Recrystallization. Use ether...

You will apply what you have learned earlier in the semester when performing the Acid-Base Extraction experiment to perform a different separation: that of an organic neutral compound and organic base. You will also need to purify and characterize these compounds. You will have one lab period to execute your plan for separating the assigned mixture given below. There will be a 1:1 (by mass) mixture placed in the lab: 1,4-dichlorobenzene/ethyl 4-aminobenzoate. You will take approximately 1 g of your...

mixture of trans-cinnamic acid,
4-phenylphenol, and nicotinamide by extraction?
thank you
Procedure Your mission is to separate a mixture of trans-cinnamic acid, 4-phenylphenol, and nicotinamide by extraction. Start by dissolving/suspending two grams of the mixture in approximately 50 mL of diethyl ether. (Caution: Diethyl ether is extremely flammable! Extract the ether twice with -25 mL of 5% HCl and then twice with -25 mL 5% sodium bicarbonate. It...

17. Draw a flow sheet to show how you would separate a mixture of benzoic acid, 2-naphthol, aniline, and naphthalene. (indicate the solvent, location and composition of each layer). Draw all balanced equations. (6') Reagents available: 3M hydrochloric acid solution, 3M sodium hydroxide solution, 3M sodium bicarbonate solution, saturated sodium chloride solution Solvent available: water, dichloromethane, ethanol, and diethyl ether.

Liquid-Liquid Extraction P14. Your instructor gives you 1g of a 50:50 mixture of the following solids and asks you to separate them from one another. First you dissolve the mixture in ether: methyl trains-cinnamate OH trans-cinnamic acid OMe mp 34-38°c mp 133°C Using what you learned in P11-P12, complete the extraction plan below (aqueous acid or base should be added?): Aqueous solution of added Top layer: circle one (aqueous or organic?)

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...

1. Write equations for the reactions that occur in the following. (a) 2-methylbutanol and acetic acid (ethanoic acid) are heated together in the presence of a small quantity of sulphuric acid. (b) Butanoic acid is added to a solution of thionyl chloride (SOCl2) and the mixture heated. After the reaction has occurred an excess of diethyl amine is added. 2. (a) How would you separate a mixture of benzoic acid and dibutyl amine, using a 1M HCl solution, a 1M...

seperation of acid neutral
Experiment 5: Separation of Acid-Neutral Mixture Post-Lab Questions 1. Draw and label the structures of the major and minor components of the acidic and neutral mixtures. 2. Although acetic acid - water may be used as a "solvent pair", why are dilute solutions of an inorganic acid/water (or, inorganic base/water) avoided in recrystallization attempts? (Hint: see Wade Ed: Sections 21-12, 21- 13. Consider functional-group possibilities.] 3. Using a flow diagram, show the separation of a mixture...
