`H_(2)O_(2)` can be obtained when following reacts with `H_(2)SO_(4)` excepts with

A

`PbO_(2)`

B

`BaO_(2)`

C

`Na_(2)O_(2)`

D

`SrO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
a
`BaO_(2)+` dil. `H_(2)SO_(4) rarr BaSO_(4)+H_(2)O_(2)`
`Na_(2)O_(2)+` dil. `H_(2)SO_(4) rarr Na_(2)SO_(4)+H_(2)O_(2)`
`SrO_(2)+`dil. `H_(2)SO_(4) rarrSrSO_(4)+H_(2)o_(2)`
`PbO_(2)+` dil`H_(2)SO_(4) rarr PbSO_(4)+H_(2)O+(1)/(2)O_(2)uarr`
`PbO_(2)+H_(2)SO_(4)` cannot give `H_(2)O_(2)` , instead of it gives `H_(2)O+(1)/(2) uarr`.
