$6.8 \, g$ of $H_2O_2$ is dissolved in $0.2 \, L$ of solution. Then the solution will be labelled as ............. $V$ volume strength.

In basic medium,$H_{2}O_{2}$ exhibits which of the following reactions?
$A$. $Mn^{2+} \rightarrow Mn^{4+}$
$B$. $I_{2} \rightarrow I^{-}$
$C$. $PbS \rightarrow PbSO_{4}$
Choose the most appropriate answer from the options given below:

Electrolysis of $X$ gives $Y$ at anode. Vacuum distillation of $Y$ gives $H_2O_2$. The number of peroxy $(O-O)$ bonds present in $X$ and $Y$ respectively are :

Assertion: The $O-O$ bond length in $H_2O_2$ is shorter than that of $O_2F_2$.
Reason: $H_2O_2$ is an ionic compound.

Which one of the following does $NOT$ readily give oxygen upon heating?

$H_2O_2$ is manufactured these days by:
