If the $K_{sp}$ of $Mg(OH)_2$ is $1 \times 10^{-12}$,at what $pH$ will $Mg(OH)_2$ precipitate from a $0.01 \ M$ solution of $Mg^{2+}$ ions?

The $K_{sp}$ of an electrolyte $AB$ is $1 \times 10^{-10}$. If $[A^{+}] = 10^{-5} \ M$,which concentration of $B^{-}$ will not result in the precipitation of $AB$?

At $298 \ K$ temperature,the solubility product $(K_{sp})$ for $AgCl$ is $1.5 \times 10^{-10}$. Calculate its solubility in $g \ L^{-1}$ in pure water. (Molar mass of $AgCl = 143.5 \ g \ mol^{-1}$)

The solubility of $AgCl$ in $0.2 \ M \ NaCl$ solution ($K_{sp}$ for $AgCl = 1.20 \times 10^{-10}$) is:

The solubility of $AgCN$ in a buffer solution of $pH = 3$ is $x$. The value of $x$ is [Assume : No cyano complex is formed; $K_{sp}(AgCN) = 2.2 \times 10^{-16}$ and $K_{a}(HCN) = 6.2 \times 10^{-10}$]

An aqueous solution contains $SCN^{-}$,$Br^{-}$,$I^{-}$,and $Cl^{-}$ ions. When $AgNO_3$ is added to the solution,which of these will precipitate first? Given: $K_{sp}(AgCl) = 1.2 \times 10^{-10}$,$K_{sp}(AgI) = 1.7 \times 10^{-16}$,$K_{sp}(AgSCN) = 7.1 \times 10^{-7}$,$K_{sp}(AgBr) = 3.5 \times 10^{-13}$.
