The oxide that gives H2O2 most readily on treatment with H2O is (1) PbO2 (2) Na2O2 (3) SnO2 (4) BaO2.8H2O

Correct answer: (2) Na2O2 Explanation: 1. PbO2 + 2H2O → Pb(OH)4 2. Na2O2 + 2H2O → 2NaOH + H2O2 this reaction is possible at room temperature 3. SnO2 + 2H2O → Sn(OH)4 4. Acidified BaO2.8H2O gives H2O2 after evaporation.

Correct answer: (2) Na₂O₂

Explanation:

1. PbO₂ + 2H₂O → Pb(OH)₄

2. Na₂O₂ + 2H₂O → 2NaOH + H₂O₂

this reaction is possible at room temperature

3. SnO₂ + 2H₂O → Sn(OH)₄

4. Acidified BaO₂.8H₂O gives H₂O₂ after evaporation.
