Question

Hydrogen peroxide is not:

• A. a reducing agent
• B. an oxidizing agent
• C. a dehydrating agent
• D. a bleaching agent

Answer 1

Answer: (C)

a dehydrating agent

Oxidation state of oxygen in $H_2{O}_2$ is $-1$ due to presence of peroxide linkage. Oxygen has an intermediate oxidation state (between $-2$ and $0$). So, further it can be oxidized (from $-1$ to $0$) as well as reduced (from $-1$ to $-2$) so it can acts as oxidising as well as reducing agent.
Also it can act as bleaching agent due to presence of available oxygen atoms.

Hence, we can conclude that $H_2{O}_2$ can act as a reducing agent, oxidizing agent and bleaching agent.
Here, the correct option will be (C)
