Question

Which one of the following reactions indicates the reducing ability of hydrogen peroxide in basic medium ? (A) HOCl + H 2 O 2 arrow H 3 O ++ Cl -+ O 2 (B) PbS +4 H 2 O 2 arrow PbSO 4+4 H 2 O (C) 2 MnO 4-+3 H 2 O 2 arrow 2 MnO 2+3 O 2+2 H 2 O +2 OH - (D) Mn 2++ H 2 O 2 arrow Mn 4++2 OH -

In option (A) and (C) reducing action of hydrogen peroxide is shown. In option (A) it is in acidic medium, in option (B) it is in basic medium. or For reducing ability H 2 O 2 changes to O 2, i.e. oxidize, so in option ' A prime C prime O 2 is formed but ' A ' is in acidic medium so option - C correct.
