Amount of oxalic acid present in a solut...

Amount of oxalic acid present in a solution can be determined by its titration with `KMnO_(4)` solution in the presence of `H_(2)SO_(4)` . The titration gives unsatisfactory result when carried out in the presence of HCl because HCl:

A

oxidises oxalic acid to carbon dioxide and water

B

reduces permanganate to `Mn^(2+)`

C

gets oxidised by oxalic acid to chlorine

D

furnishes `H^(+)` ions in addition to those from oxalic acid.
