Text Solution
Verified by ExpertsThe correct answer is:
3
(3) In Faintly alkaline medium potassium permanganate changes to manganese dioxide in its oxidising action.

The oxidation state of manganese in
is +7 and in MnO 2 is +4.
Hence, it transfers 3 electrons during the oxidising action in alkaline medium
