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.
