Question

Amount of oxalic acid present in a solution can be determined by its titration with $\mathrm{KMnO}_4$ solution in the presence of $\mathrm{H}_2 \mathrm{SO}_4$. The titration gives unsatisfactory result when carried out in the presence of HCl , because HCl

(d) : Oxalic acid present in a solution can be determined by its titration with $\mathrm{KMnO}_4$ solution in the presence of $\mathrm{H}_2 \mathrm{SO}_4$. Titration cannot be done in the presence of HCl because $\mathrm{KMnO}_4$ being a strong oxidising agent oxidises HCl to $\mathrm{Cl}_2$ and gets itself reduced to $\mathrm{Mn}^{2+}$. So actual amount of oxalic acid in solution cannot be determined.
