Salts of carboxylic acids can be converted into corresponding carboxylic acid by treating with:
Correct answer: D. Acid
- A. Water
- B. Base
- C. Acid anhydrides
- D. Acid
Explanation
The appropriate ester on boiling with concentrated sodium hydroxide yields sodium salt of the acid.This resulting salt when treated with dilute HC1 gives the free carboxylic acid.(PTB Chapter 13: Carboxylic acids and their derivatives).

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
