MCQ

Pick out the incorrect statement :

A
$MnO_4^{2-}$ is quite strongly oxidizing and stable only in very strong alkalies. In dilute alkali, neutral solutions, it disproportionates.
B
In acidic solutions, $MnO_4^{2-}$ is reduced to $Mn^{2+}$ and thus, $KMnO_4$ is widely used as oxidising agent
✓
$KMnO_4$ does not acts as oxidising agent in alkaline medium
D
$KMnO_4$ is manufactured by the fusion of pyrolusite ore with $KOH$ in presence of air or $KNO_3,$ followed by electrolytic oxidation in alkaline solution.

✓

Answer

Correct option: C.

$KMnO_4$ does not acts as oxidising agent in alkaline medium
