Which one of the following reactions indicates the reducing ability of hydrogen peroxide in basic medium?

Options

AHOCl + H 2 O 2 → H 3 O + + Cl - + O 2
BPbS + 4 H 2 O 2 → PbSO 4 + 4 H 2 O
C2 MnO 4 - + 3 H 2 O 2 → 2 MnO 2 + 3 O 2 + 2 H 2 O + 2 OH -
DMn 2 + + H 2 O 2 → Mn 4 + + 2 OH -

Correct answer

C. 2 MnO 4 - + 3 H 2 O 2 → 2 MnO 2 + 3 O 2 + 2 H 2 O + 2 OH -

Step-by-step solution

In option A and C reducing action of hydrogen peroxide is shown. For reducing ability H 2 O 2 changes to O 2 , i.e. oxidize, so in option ' A ' & C ' ' O 2 is formed but ' A ' is in acidic medium so option - C is correct. 2 MnO 4 - + 3 H 2 O 2 → 2 MnO 2 + 3 O 2 + 2 H 2 O + 2 OH -
