In which of the following reactions, H2O2 acts as a reducing agent? (EAMCET 2014) (a) H HOCl H O H O Cl O -> (b) OH Mn H O Mn 2OH -> (c) OH 2Fe H O 2Fe 2OH -> (d) H PbS s 4H O aq PbSO s 4H O l ->

Due to electron donating property of H2O2, it acts as a reducing agent in acidic as well as in alkaline medium and gets oxidised to O2. 2 2 3 2 H HOCl H O H O Cl O -> On the other hands, its reaction with Mn2+, Fe2+ and PbS, show its oxidizing property in which it reduces to H2O.
