If the solubility product of $Ni(OH)_2$ is $4.0 \times 10^{-15}$,the solubility (in $mol \ L^{-1}$) is

Let the solubility of an aqueous solution of $Mg(OH)_2$ be $x$,then its $K_{sp}$ is:

At $30\,^{\circ}C,$ the solubility of $Ag_2CO_3$ $(K_{sp} = 8 \times 10^{-12})$ would be greatest in one litre of

Calculate the solubility of $A_{2}X_{3}$ in pure water,assuming that neither kind of ion reacts with water. The solubility product of $A_{2}X_{3}$,$K_{sp} = 1.1 \times 10^{-23}$.

If equal volumes of $AB_2$ and $XY$ (both are salts) aqueous solutions are mixed,which of the following combinations will give a precipitate of $AY_2$ at $300 \ K$? (Given $K_{sp}$ (at $300 \ K$) for $AY_2 = 5.2 \times 10^{-7}$)

In which of the following solutions will the solubility of $Ag_2CO_3$ $(K_{sp} = 8 \times 10^{-12})$ be maximum at $30 \, ^\circ C$?
