Pick out the incorrect statement:

Question

Pick out the incorrect statement: (A) MnO 42- is quite strongly oxidizing and stable only in very strong alkalies. In dilute alkali, neutral solutions, it disproportionates. (B) In acidic solutions, MnO 4-is reduced to Mn 2+ and thus, KMnO 4 is widely used as oxidising agent (C) 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 acidic medium

Correct answer is (c) KMnO 4 does not acts as oxidising agent in alkaline medium

Q. Pick out the incorrect statement:

$M n O_{4}^{2 -}$ is quite strongly oxidizing and stable only in very strong alkalies. In dilute alkali, neutral solutions, it disproportionates.

In acidic solutions, $M n O_{4}^{-}$ is reduced to $M n^{2 +}$ and thus, $K M n O_{4}$ is widely used as oxidising agent

$K M n O_{4}$ does not acts as oxidising agent in alkaline medium

$K M n O_{4}$ is manufactured by the fusion of pyrolusite ore with $K O H$ in presence of air or $K N O_{3}$ , followed by electrolytic oxidation in acidic medium

Correct answer is (c) $K M n O_{4}$ does not acts as oxidising agent in alkaline medium
