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
c
