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
Homework Answers
Option D, an amine hydrochloride salt since amine reacts with HCl and forms salt which is soluble in aqueous medium.

Extraction of benzoic acid and 9-fluorenone using diethyl ether. (please do not include ethyl 4- aminobenzoate). I have to create a flow chart to diagram the key steps of the experiment and isolation of products. 0.100g of benzoic acid and 9-fluorenone are dissolved in diethyl ether. The extraction solvent is 5% sodium hydroxide (to extract the acidic component from the organic phase). Saturated sodium chloride is added to the organic layer. drying the organic solution: anhydrous sodium sulfate is added...

Please, write out the balanced chemical reactions used to sequentially extract the carboxylic acid and the phenol from the organic phase into aqueous phases, and then precipitate them upon acidification of the aqueous phases, using the information below. 1st) You will prepare an ether solution (the organic phase) of the two compounds; any minor impurities are non-acidic and will remain dissolved in the organic phase throughout the extraction process. 2nd) You will extract benzoic acid from the organic (ether) phase...

An unknown mixture (dissolved in diethyl ether) contains only 2 of the following : benzoic acid, phenol, aniline and napthalene. You use the acid-base extraction method and want to identify the 2 compounds in your original mixture. 1) To separate the organic acid you add NaOH and to separate the organic base you add HCl.In both cases these extractions are followed by extractions with water. Why do we add water? Why is this step important? (A clear explanation please). 2)When...

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.

In the acid/base extraction lab, a carboxylic acid was separated
from fluorene by extracting the carboxylic acid into the aqueous
layer using NaOH solution (a review of this experiment before lab
will be helpful). Phenols (aromatic alcohols) can also be separated
using this method. In a mixture of a phenol and a non-reacting
organic compound, the phenol may be selectively removed from an
organic solvent by extracting with a dilute NaOH solution. After
separating the organic and aqueous layers, the...
