In laboratory, manganese (II) ion salt is oxidised to permanganate ion in aqueous solution by peroxodisulphate.
$2{\mathrm{Mn}}^{2+}+\underset{\text{peroxodisulphate ion}}{5{\mathrm{S}}_2{\mathrm{O}}_8^{2-}}+8{\mathrm{H}}_2\mathrm{O}\to$ $2{\mathrm{MnO}}_4^{-}+10{\mathrm{SO}}_4^{2-}+16{\mathrm{H}}^{+}$
