Question

On cooling a saturated solution of $Pb{Cl}_2$, the solution becomes rich in ${Pb}^{2+}$ ions. If true write 1, else write 0.

Answer 1

On cooling a saturated solution of $Pb{Cl}_2$, the solution becomes poor in ${Pb}^{2+}$ ions as the solubility product value decreases due to which solubility decreases.
