The oxide that gives $H_{2}O_{2}$ most readily on treatment with $H_{2}O$ is:

Which of the following cannot be reduced by $H_2O_2$?

$10 \, mL$ of $H_2O_2$ solution $(d = 1 \, g/mL)$ when reacted with $KI$ solution produced $0.5 \, g$ of iodine. Calculate the percentage purity of $H_2O_2$ .............. $\%$

Hydrogen peroxide $(H_2O_2)$ is:

The strengths of $5.6$ volume hydrogen peroxide (of density $1 \ g/mL$) in terms of mass percentage and molarity $(M)$,respectively,are:
(Take molar mass of hydrogen peroxide as $34 \ g/mol$)

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 $3.03\% \ (w/v) \ H_2O_2$.
