Question

This section contains questions each with two columns-I and II. Match the sparingly soluble salt given in column I with their solubility in column II.

Answer 1

(A) Solubility of AgCl in 0.1 M HCl is given by the expression$\frac{K_{sp}}{0.1}$.
(B) Solublity of $Ni(OH{)}_2$ in 0.1 M NaOH is given by the expression $\frac{K_{sp}}{(0.1{)}^2}$.
(C) Solubility of $Ni(OH{)}_2$ in $NiC{l}_2$ is given by the expression ${\left(\frac{K_{sp}}{4\times 0.1}\right)}^{1/2}$.
(D) Solubility of $Al(OH{)}_3$ in 0.1 M NaOH is given by the expression $\frac{K_{sp}}{(0.1{)}^3}$.
(E) Solubility of AgCN in a buffer solution of pH = 3 is given by the expression $\left[K_{sp}(1+\frac{H^{\oplus }}{K_a})\right]$.
