MCQ
From the following statements regarding $\ce{H_2​O_2}$, choose the incorrect statement:
  • ✓
    It can act only as an oxidising agent.
  • B
    It decompose 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

Correct option: 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 $-2.$
Thus, statement $(1)$ is incorrect. Rest of the given statements are correct.
