Question

From the following statements regarding $H_2{O}_2$, choose the incorrect statement.

• A. It can act only as an oxidising agent
• B. It decomposes on exposure to light
• C. It has to be stored in plastic or wax lined glass bottles in dark
• D. It has to be kept away from dust

Answer 1

The correct option is A

It can act only as an oxidising agent

$H_2{O}_2$ acts as an oxidising as well as reducing agent, because oxidation number of oxygen in $H_2{O}_2$ is -1. So, it can be oxidised to oxidation state 0 or reduced to oxidation state -2.

$H_2{O}_2$ decomposes on exposure to light. So, it has to be stored in plastic or wax lined glass bottles in dark for the prevention of exposure. It also has to be kept away from dust.
