$\underset{}{\underbrace{\mathrm{M}\mathrm{n}{\mathrm{O}}_4^{-}+8{\mathrm{H}}^{+}}}\to \underset{+2}{\underbrace{\mathrm{M}{\mathrm{n}}^{2+}}}+4{\mathrm{H}}_2\mathrm{O}$
To balance charge on both sides add$5{\mathrm{e}}^{!}$to L.H.S.
${\text{MnO}}_{\text{4}}^{-}\text{+}{\text{8H}}^{\oplus }\text{+}{\text{5e}}^{-}\to {\text{Mn}}^{\text{2+}}\text{+}{\text{4H}}_{\text{2}}\text{O}$
