$H_2O_2$ is manufactured these days by:

Match List $I$ with List $II$ and select the correct answer using the codes given below the lists:

$A$. Peroxide	$1$. $C_3O_2$
$B$. Superoxide	$2$. $PbO_2$
$C$. Dioxide	$3$. $KO_2$
$D$. Suboxide	$4$. $H_2O_2$

On reaction with a stronger oxidizing agent like $KIO_{4}$,hydrogen peroxide is oxidized with the evolution of $O_{2}$. The oxidation number of $I$ in $KIO_{4}$ changes to $..........$

The $pH$ of a solution of $H_2O_2$ is $6.0$. Some chlorine gas is bubbled into this solution. Which of the following is correct?

The correct statements among the following are
$i$. Saline hydrides produce $H_2$ gas when reacted with water
$ii$. Presently $\sim 77 \%$ of the industrial dihydrogen is produced from coal
$iii$. Commercially marketed $H_2O_2$ contains $3 \% H_2O_2$

Consider the following statements:
Statement-$I$: $H_2O_2$ acts as an oxidising as well as a reducing agent in both acidic and basic media.
Statement-$II$: $10 \ V \ H_2O_2$ sample means it contains $3.03\% \ (w/v) \ H_2O_2$.
