Question

Verified Solution • 2025–26 Session moderate

Amount of oxalic acid present in a solution can be determined by its titration with

KMn{O_4}

solution in the presence of

{H_2}S{O_4}.

The titration gives unsatisfactory result when carried out in the presence of

HCl,

because

HCl

:

Accepted Answer

The titration of oxalic acid with

KMnO{}_4

in presence of

HCl

gives unsatisfactory result because of the fact that

KMn{O_4}

can also oxidise

HCl

along with oxalic acid.

HCl

on oxidation gives

C{l_2}

and

HCl

reduces

KMnO{}_4

to

M{n^{2 + }}

thus the correct answer is

(c).
