Question

Potassium permanganate acts as an oxidant in neutral, alkaline as well as acidic media. The final products obtained from it in the three conditions are, respectively, M n O 4 2 - , M n 3 + and M n 2 +, M n O 2 , M n O 2 and M n 2 +, M n O 2 , M n O 2 + and M n 2 +, MnO, MnO 2 and M n 2 +

MARKS App · Accepted Answer

In neutral and alkaline medium M n O 4 - + 2 H 2 O + 3 e - → M n O 2 + 4 O H - In acidic medium M n O 4 - + 8 H + + 5 e - → M n 2 + + 4 H 2 O
