Vedclass · Answer

(C) The statement in option $C$ is incorrect because $KMnO_4$ acts as a strong oxidizing agent in an alkaline medium,where it is reduced to $MnO_4^{2-}$ (manganate ion). Option $A$ is correct as $MnO_4^{2-}$ is stable only in strongly alkaline solutions and disproportionates in neutral or acidic media. Option $B$ is correct as $KMnO_4$ is a powerful oxidizing agent in acidic media,reducing to $Mn^{2+}$. Option $D$ is correct as it describes the standard industrial preparation of $KMnO_4$ from pyrolusite $(MnO_2)$.
