Question

Is ${\mathrm{PbCl}}_2$ soluble in water?

Answer 1

1. The compounds which are soluble in water and which one is insoluble in water depend upon the solubility of that particular substance.
2. The solubility product of ${\mathbf{PbCl}}_{\mathbf{2}}$ is $\mathbf{1}\mathbf{.}\mathbf{7}\mathbf{\times }{\mathbf{10}}^{\mathbf{-}\mathbf{5}}$ at a normal temperature.
3. The solubility product shows that lead chloride is less soluble in water.

Hence, ${\mathbf{PbCl}}_{\mathbf{2}}$ is not completely soluble in water, it is a sparingly soluble salt.
