Which of the following equations depict the oxidising nature of H2 O2?
A. 2[Fe(CN)6]4 + 2H+ + H2O2→ 2[Fe(CN)6]3- + 2H2O
B. I2 + H2 O2 +2OH-→ 2I- + 2H2O + O2
C. Mn2+ + H2O2→ Mn-4 + 2OH-
D. KIO4 + H2O2→ KIO3 + H2O + O2
In the reaction where ferrocyanide ion reacts with hydrogen peroxide, the oxidation state on ferrocyanide ion is +2 and it increases to +3 in ferricyanide ion in the product. So, here hydrogen peroxide acts as an oxidising agent.
