Which metal oxide among the following gives H 2 O 2 on treatment with dilute acid?
Options
- ABaO 2
- BRbO 2
- CMnO 2
- DAl 2 O 3
Correct answer
A. BaO 2
Step-by-step solution
The oxide that gives H 2 O 2 on treatment with dilute acid is BaO 2 because BaO 2 contains superoxide ions When barium superoxide is treated with dilute acid then it gives oxide and hydrogen peroxide BaO 2   +   H 2 SO 4   →   BaSO 4   +   H 2 O 2
