How is hydrogen peroxide commercially prepared by electrolysis of `H_2 SO_4` solution ? How is it concentrated ? Explain its oxidising and reducing character .

Hydrogen can be prepared by the action of dil. H_(2)SO_(4) on

In which of the solution hydrogen peroxide neither acts as oxidising agent nor reducing agent ?

How does hydrogen peroxide behave in the reaction with KIO_(4)

Hydrogen peroxide can be prepared by the action of dil. H_(2)SO_(4) or H_(3)PO_(4) on barium peroxide or by bubbling carbon dioxide through a thin paste of barium peroxide. On an industrial scale , it can be prepared by hydrolysis of peroxodisulphuric acid obtained by electrolysis of 50% H_(2)SO_(4) or an equimolar mixture of H_(2)SO_(4) and ammonium sulphate .The strength of H_(2)O_(2) solution can be expressed in a number ways namely normality , molarity , percentage strength and volume of O_(2) produced at N.T.P by decomposition of 1 mL of H_(2)O_(2) acts as an oxidising as well a reducing agent both in acidic and basic media. Hydrogen peroxide is used as
