The solubility of silver chromate in $0.01 \, M$ $K_2CrO_4$ is $2 \times 10^{-8} \, mol \, dm^{-3}$. The solubility product of silver chromate will be

An acidified solution of $0.05 \ M \ Zn^{2+}$ is saturated with $0.1 \ M \ H_2S$. What is the minimum molar concentration $(M)$ of $H^{+}$ required to prevent the precipitation of $ZnS$? Use $K_{sp}(ZnS) = 1.25 \times 10^{-22}$ and overall dissociation constant of $H_2S$,$K_{NET} = K_1 K_2 = 1 \times 10^{-21}$.

Which of the following is the correct formula for the ionic product $(K_{sp})$ of $SnS_2$ (stannic sulfide)?

Assign $A$,$B$,$C$,$D$ from the given type of reaction.
