An acid-base extraction can be used to extract carboxylic acids from the organic layer into the aqueous layer. 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.

Solved Experiment 5- Separation of Organic Compounds - Chegg
In this experiment you will use extraction techniques to separate a mixture of an organic acid, a base, and a neutral compound. Organic acids and bases can be separated from each other and from neutral compounds by extraction using aqueous solutions of different pH values.
2.1: Separation of an Unknown Mixture by Acid/Base Extraction
Acid/Base Extraction Flow chart References Experimental Aims : The objective of this exercise is to separate a two-component mixture using extraction techniques and then to identify the isolated components by determining their melting points.
The flow chart on the next page outlines a general procedure for separating acidic, basic and neutral organic compounds using the principles of the solubility switch. You will separate a mixture that contains benzoic acid, 4-chloroaniline and naphthalene. The 4-chloroaniline is separated first by extraction with hydrochloric acid.

Two Base Extraction Introduction : Given a 2 gram sample of a mixture containing benzoic acid, 2-naphthol, and naphthalene, we are to separate each part. Procedure : 1. The mixture is dissolved in 30 ml of diethyl ether. 2. 20 ml of 10% Bicarbonate is added to the solution in a separatory funnel where the aqueous
