InterviewSolution

1.	A is a lighter phenol and B is an aromatic carboxylic acid . Separation of a mixture of A and B can be carried out easily by using a solution ofA. sodium hydroxideB. sodium sulphateC. calcium chlorideD. sodium bicarbonate
Answer» Correct Answer - D Carboxylic acids are soluble in sodium bicarbonate but phenol are not dissolve in it , so they are separated because carboxylic acid react with `NaHCO_(3)` and form sodium carboxylate `R-COOH + NaHCO_(3) to R-COO^(-)Na^(+) + H_(2)CO_(3)`
