Consider the equilibrium of PbCl2(s) in water: PbCl2(s) Pb2+(aq) + 2Cl-(aq) What is the effect of adding NaCl(aq) to the equilibrium solution? The sodium ion reduces the Pb2+ to Pb(s). PbCl2 solubility increases due to the common-ion effect. PbNa2(s) precipitates. The NaCl(aq) has no effect on the system. PbCl2(s) precipitates until equilibrium is reestablished.
