Question

In which of the following reactions, H2O2 acts as
oxidizing agent?
1) 2NaOH + H2O2 → Na2O2 +2H2O
2) KNO2 + H2O2 → KNO3 +H20
3) Cl2 + H2O2 → 2HCI + O2
4) Ag2O + H2O2 + 2Ag + H2O + O2 moist​

Answer 1

Answer:

2nd

Explanation:

it probably acts in 1st and 2nd but 1st reaction is not possible. 3rd reaction is reduction and 4th is probably done under action of heat and is decomposition reaction.

Answer 2

Answer is 2nd ≈ KNO2+H2O2→KNO3+H2O
