The $K_{sp}$ expression for $Ca_3(PO_4)_2$ is:

Find the solubility of $PbI_2$ if its solubility product is $7.0 \times 10^{-9}$.

The concentration of $KI$ and $KCl$ in a solution containing both is $0.001 \ M$ each. If $20 \ mL$ of this solution is added to $20 \ mL$ of a saturated solution of $AgI$ in water,what will happen?

The solubility product constants $(K_{sp})$ for some silver salts are given as: $AgCl = 2 \times 10^{-10}$,$AgBr = 5 \times 10^{-13}$,$Ag_2CO_3 = 8 \times 10^{-12}$,and $AgI = 8 \times 10^{-17}$. Which of the following salts has the highest solubility?

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 $AY_2 = 5.2 \times 10^{-7}$)

At $T(K)$,the solubility product of $AgBr$ is $4 \times 10^{-13}$. What is its solubility in $0.1 \ M$ $KBr$ solution?
