The solubility of carboxylic acid in water gradually decreases with:
Correct answer: B. Increases in molecular mass
- A. Decreases in molecular mass
- B. Increases in molecular mass
- C. Increases the amount of acid
- D. Decreases the amount of water
Explanation
Increases in molecular mass - Correct. Higher molecular mass acids have larger nonpolar hydrocarbon chains, reducing solubility.

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.
