2 moles of equimolar mixture of ${\mathrm{Na}}_2{\mathrm{C}}_2{\mathrm{O}}_4$ and ${\mathrm{H}}_2{\mathrm{C}}_2{\mathrm{O}}_4$ required ${\mathrm{V}}_1\mathrm{L}$ of $0.1\mathrm{M}{\mathrm{KMnO}}_4$ in acidic medium for complete oxidation. The same amount of the mixture required ${\mathrm{V}}_2\mathrm{L}$ of 0.2 M NaOH for complete titration. The ratio of $V_1$ to $V_2$ is:
