Auto-oxidation of bleaching powder gives:

$1 \text{ mole}$ of $MnO_4^{2-}$ disproportionates into $MnO_4^-$ and $MnO_2$ in an acidic medium. Calculate the percentage by mass of $Mn$ converted to $MnO_4^-$ (Molar mass of $Mn = 55 \ g/mol$).

The reaction $Cl_2 + 2OH^{-} \to ClO^{-} + Cl^{-} + H_2O$ represents the process of bleaching. Identify and name the species that bleaches the substances due to its oxidising action.

In the following reaction,$4P + 3KOH + 3H_2O \to 3KH_2PO_2 + PH_3$,what happens to phosphorus $(P)$?

Which of the following species can function both as an oxidizing as well as a reducing agent?

When $Cl_2$ gas is passed through a hot and concentrated solution of $KOH$,which of the following compounds is formed?
