Strength of a $H_2O_2$ solution is labelled as $1.79 \, N$. Its strength can also be expressed as closest to $... \, \text{volume}$.

$H_2O_2$ is always stored in wax-lined black bottles because:

In which of the following reactions,$O_2$ is not liberated?

$H_2O_2$ is manufactured these days by

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 :

$H_2O_2$ reacts as a reducing agent with:
$(I)$ $KMnO_4$
$(II)$ $K_2Cr_2O_7$
$(III)$ $Ag_2O$
$(IV)$ $HNO_3$
