`HCl` is added to following oxides. Which one would give `H_(2)O_(2)` ?

A

`MnO_(2)`

B

`PbO_(2)`

C

`BaO`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
d
`MnO_(2),PbO_(2)` and `BaO` will not give `H_(2)O_(2)` with `HCl. MnO_(2)` and `PbO_(2)` will give `Cl_(2)` and `BaO` will react with `HCl` to give `BaCl_(2)` and water.
