Hydrogen peroxide in its reaction with \[KI{{O}_{4}}\] and \[N{{H}_{2}}OH\] respectively, is acting as a

A) Reducing agent, oxidising agent

B) Reducing agent, reducing agent

C) Oxidising agent, oxidising agent

D) Oxidising agent, reducing agent

Correct Answer: A

Solution :

\[{{\operatorname{KIO}}_{4}}+{{\operatorname{H}}_{2}}{{O}_{2}}\to {{\operatorname{KIO}}_{3}}+{{\operatorname{H}}_{2}}O+{{O}_{2}}\]

Thus\[{{\operatorname{H}}_{2}}{{O}_{2}}\] is acting as a reducing agent

\[2N{{H}_{2}}OH+{{H}_{2}}{{O}_{2}}\to {{N}_{2}}+4{{H}_{2}}O\]

Here \[{{\operatorname{H}}_{2}}{{O}_{2}}\] is acting as an oxidising agent.
