$\mathrm{K}\mathrm{M}\mathrm{n}{\mathrm{O}}_4$can be prepared from${\mathrm{K}}_2\mathrm{M}\mathrm{n}{\mathrm{O}}_4$as per the reaction
$3\mathrm{M}\mathrm{n}{\mathrm{O}}_4^{2-}+2{\mathrm{H}}_2\mathrm{O}\rightleftharpoons 2\mathrm{M}\mathrm{n}{\mathrm{O}}_4^{-}+\mathrm{M}\mathrm{n}{\mathrm{O}}_2+4\mathrm{O}{\mathrm{H}}^{-}$
The reaction can go to completion by removing$\mathrm{O}{\mathrm{H}}^{-}$ions by adding
