Q. 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 of

AIPMTAIPMT 1992Aldehydes Ketones and Carboxylic Acids

Solution:

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.
$R \, - \, COOH + NaHCO_3 \rightarrow R \, - \, COONa$
$ +H_2CO_3$
