${\text{3MnO}}_{\text{4}}^{-\text{2}}\text{+}{\text{4H}}^{\text{+}}\to {\text{2MnO}}_{\text{4}}^{-}\text{+}{\text{MnO}}_{\text{2}}\text{+}{\text{2H}}_{\text{2}}\text{O}$
$\mathrm{M}\mathrm{n}{\mathrm{O}}_4^{2-}$in neutral aqueous medium is disproportionate to$\frac{2}{3}$mole of$\mathrm{M}\mathrm{n}{\mathrm{O}}_4^{-}$and$\frac{1}{3}$mole of$\mathrm{M}\mathrm{n}{\mathrm{O}}_2$.
