Question

Formic acid can be distinguished from acetic acid by reacting with (A)  NaHCO3  (B) dil. acidified KMnO4 solution (C)  2 , 4 -dinitrophenyl hydrazine (D)  Na metal

Tardigrade Admin · Accepted Answer

Formic acid can be distinguished from acetic acid since it contains a hydrogen atom instead of methyl group. Therefore, formic acid acts as a reducing agent and decolorise acidified

K M n O_{4}

solution.

H COO H - [O] K M n O_{4} Acidified carbonic add [H O - CO - O H]

\to C O_{2} + H_{2} O
