Hydrogen peroxide can be preapared bythe action of dil. H_(2)SO_(4) or H_(3)PO_(4) on barium peroxide or by bubbling 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 of ways namely normality , molarity , percentage strength and volume strength . Volume strength refers to the volume of O_(2) produced at N.T.P. by decomposition of 1 mL of H_(2)O_(2) solution. H_(2)O_(2) acts as an oxidising as well as reducing agent both in acidic and basic media. Which of the following substances on treatment with H_(2)O_(2) gives MnO_(2)
