1.	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
Answer» `PbO_(2)` `MnO_(4)` `TiO_(4)` `KO_(2)` SOLUTION :The compound wich GIVES `H_(2)O_(2)` on tratement with acid is `KO_(2)`
