$\text{milli}\text{eq}\text{.}\text{of}{\text{KHC}}_{\text{2}}{\text{O}}_{\text{4}}\text{=}\text{milli}\text{eq}\text{.}\text{of}{\text{KMnO}}_{\text{4}}$
$({\mathrm{C}}^{3+}{)}_2\to 2{\mathrm{C}}^{4+}+2\mathrm{e}$
$\mathrm{M}{\mathrm{n}}^{7+}+5\mathrm{e}\to \mathrm{M}{\mathrm{n}}^{2+}$
$\frac{\mathrm{a}}{\frac{\mathrm{M}}{2}}\times 1000=100\times 0.02\times 5$
$\mathrm{a}=5\times 10^{–3}\mathrm{M}$
$\text{milli}\text{eq}\text{.}\text{of}{\text{KHC}}_{\text{2}}{\text{O}}_{\text{4}}\text{=}\text{milli}\text{eq}\text{.}\text{of}{\text{Ca(OH)}}_{\text{2}}$
$\mathrm{K}\mathrm{H}{\mathrm{C}}_2{\mathrm{O}}_4$acts as acidic salt
$\frac{\mathrm{b}}{\frac{\mathrm{M}}{1}}\times 1000=100\times 0.02\times 2$
$\mathrm{b}=4\times 10^{–3}\mathrm{M}$
$\frac{\mathrm{a}}{\mathrm{b}}=\frac{5}{4}$
