Hydrogen peroxide is an hydride of oxygen with formula ( mathrm{H}_{2} mathrm{O}_{2} )..It has an ability to act as oxidising as well as reducing agent both in acidic as well as in basic medium. Oxidising Nature- 1. It oxidised black lead sulphide to white lead sulphate. ( mathrm{PbS}+4 mathrm{H}_{2} mathrm{O}_{2} ) - - - - - - - - - - - -> ( mathrm{PbSO}_{4}+4 mathrm{H}_{2} mathrm{O} ) 2.Oxidises nitrites to nitrates. ( mathrm{NO}_{2}^{-}+mathrm{H}_{2} mathrm{O}_{2} ) - - ( mathrm{NO}_{3}^{-}+mathrm{H}_{2} mathrm{O} ) Reducing Nature- 1. Reduces moist silver oxide to sliver. ( mathrm{H}_{2} mathrm{O}_{2}+mathrm{Ag}_{2} mathrm{O} ) - ( mathrm{Ag}+mathrm{H}_{2} mathrm{O}+mathrm{O}_{2} ) 2.Reduecs chlorine to hydrogen chloride ( mathrm{Cl}_{2}+mathrm{H}_{2} mathrm{O}_{2} ) - - - - - - - - - - - - -> ( 2 mathrm{HCl}+mathrm{O}_{2} )
