An aqueous solution of H_(2)O_(2) is purified by

When treated with H_(2)O_(2) aqueous KMnO_(4) in acidic medium gives finally

In the reactant of KMnO_(4) with an oxalate in acidic medium. MnO_(4)^(-) is reduced to Mn^(2+) and C_(2)O_(4)^(2-) is oxidised to CO_(2) . Hence, 50 ml of 0.02 M KMnO_(4) is equivalent to

2H_(2) O_(2) to 2 H_(2)O_ + O_(2) . This reaction is

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
