$H_2O_2$ can be used as:

To an aqueous solution of $AgNO_3$,some $NaOH_{(aq)}$ is added until a brown precipitate is obtained. To this,$H_2O_2$ is added dropwise. The precipitate turns black with the evolution of $O_2$. The black precipitate is:

$KO_2 + H_2O \to KOH + O_2 +$ product $(X)$. Choose the correct statement about product $(X)$.

All the products formed in the oxidation of $NaBH_4$ by $I_2$ are

The $K_a$ of $H_2O_2$ is of the order of:

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