Give 1 pH value where benzoic acid and aniline would be in different layers in an extraction. Assume that possible pH values are between 0 and 14.

Benzoic acid pH range: 3 - 5

Aniline pH range: 7.5 - 8

Explanation:

pH is the measure of the acidity or alkalinity of a solution. pH value ranges between 0 - 14.

Solution with lower pH range are said to be more acidic, while the solution with high pH range are more alkaline.

Benzoic acid, being an aromatic compound is relatively acidic in nature. While aniline being an amine compound is a weak alkaline compound
