Asked by Topperlearning User | 30 May, 2016, 04:19: PM
Expert Answer
H2O2 acts as an oxidising as well as reducing agent in both acidic and alkaline media.
(i) Oxidising action in acidic medium
2Fe+2(aq) + 2H+ (aq) + H2O2(aq) → 2Fe+3 + 2H2O (l)
PbS(s) + 4H2O2 (aq) → PbSO4 (aq) + 4H2O(l)
(ii) Reducing action in acidic medium
2Fe+2(aq) + H2O2(aq) →2Fe+3 + 2OH- (l)
Mn+2 + H2O2(aq) → Mn+2 + 2OH- (l)
