Which of the of the following statements in not correct?

A
The solubility of $PbS$ in water as computed from solubility product is not affected if the hydrolysis of ${Pb}^{2 +} and S^{2 -}$ are also considered
B
The solubility of a sparingly soluble salt in water decreases if some common ion is present in water
C
The solubility product of a salt is dependant on temperature
D
The solubility of $Zn {(OH)}_{2}$ in water is dependant on the pH of the solution

Solution:

The solubility of $PbS$ is increased if the hydrolysis of ${Pb}^{2 +} and S^{2 -}$ ions are also considered. The solubility of $Zn {(OH)}_{2}$ is pH dependent due to the reaction between ${OH}^{-}$ from $Zn {(OH)}_{2}$ and $H^{+}$ ions (i.e. pH) present in the solution.

Solution:
