    A) By the action of \[{{H}_{2}}{{O}_{2}}\] on \[Ba{{O}_{2}}\]

    B) By the action of \[{{H}_{2}}S{{O}_{4}}\] on \[N{{a}_{2}}{{O}_{2}}\]

    C) By electrolysis of 50% \[{{H}_{2}}S{{O}_{4}}\]

    D) By burning hydrogen in excess of oxygen

    Correct Answer: C

    Solution :

    Electrolysis of 50% sulphuric acid gives per disulphuric acid \[({{H}_{2}}{{S}_{2}}{{O}_{8}})\] which on distillation yields 30% solution of hydrogen peroxide.
