What is the n-factor of KMnO4KMnO_4 when it acts as an oxidizing agent in a strongly alkaline medium to form K2MnO4K_2MnO_4?

  1. A.1Correct answer
  2. B.3
  3. C.5
  4. D.7

Solution

In strongly alkaline medium, KMnO4KMnO_4 is reduced to K2MnO4K_2MnO_4. The change in oxidation state of manganese is from +7 (in MnO4−MnO_4^-) to +6 (in MnO42−MnO_4^{2-}). Therefore, the change per molecule is 1, so the n-factor is 1.
