$O {H}^{-}$
$O {H}^{-}$ is the more reactive ion. KOH is quite completely dissociated and if $O {H}^{-}$ is in a great concentration it can react with metals and with inorganic and organic compounds. ${K}^{+}$, instead is called spectator ion. It doesn't react with any ion. It doesn't form insoluble compounds with any anion, It can't reduce itself; it does not form coordination compounds
