Peroxide bond is present in

$A$ : The $O-O$ bond length in $H_2O_2$ is smaller than that in $O_2F_2$.
$R$ : $H_2O_2$ is an ionic compound.

Why is hydrogen peroxide stored in wax-lined bottles?

The correct statements about $H_2O_2$ are:
$A$. Used in the treatment of effluents.
$B$. Used as both oxidising and reducing agents.
$C$. The two hydroxyl groups lie in the same plane.
$D$. Miscible with water.
Choose the correct answer from the options given below:

Decomposition of $H_2O_2$ is prevented by

Rohan heard that instructions were given to the laboratory attendant to store a particular chemical,i.e.,keep it in the dark room,add some urea in it,and keep it away from dust. This chemical acts as an oxidising as well as a reducing agent in both acidic and alkaline media. This chemical is important for use in the pollution control treatment of domestic and industrial effluents.
$(i)$ Write the name of this compound.
$(ii)$ Explain why such precautions are taken for storing this chemical.
