Hydrogen peroxide can be prepared by action of dil H_(2)SO_(4) or H_(3)PO_(4) on barium peroxide or by bubbling CO_(2) through a thin paste of barium peroxide. On industrial scale, it may be prepared by hydrolysis of peroxy disulphuric acid obtained by electrolsis of50%""H_(2)SO_(4) or equimolar mixture of sulphuric acid and ammonium sulphate. The strength ofH_(2)O_(2) can be expressed in various methods say normality, molarity, strength and volume strength. Volume strength means the volume of O_(2) produced by decomposition of 1 ml of H_(2)O_(2). H_(2)O_(2) acts as an oxidising as well as a reducing agent both in acidic and basic media. Hydrolysis of one mole of peroxodisuphuric acid produces |
