Pure `H_(2)O_(2)` is not very stable and decomposes in the presence of light or on standing or heating
`overset((-1))(H_(2)O_(2l))+overset((2-)) (H_(2)O_((l)))+overset((0))(O_(2(g)))`
The oxidation state of oxygen in `H_(2)O_(2)` is 1 it is oxidistion state of zero in `O_(2)` and is reduced to an oxidation state of -2 in `H_(2)O`. Thus, this decomposition is an example of auto oxidation reduction reaction or disproportionation reaction.
The compound which gives `H_(2)O_(2)` on treatment with dilute acid is

A

`PbO_(2)`

B

`MnO_(4)`

C

`TiO_(4)`

D

`KO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
The compound wich gives `H_(2)O_(2)` on tratement with acid is `KO_(2)`
