Consider the equilibrium of lead sulfide,PbS,in water. PbS(s) ? Pb 2+ (aq)+ S 2 ? (aq), What is the effect of adding PbS(s)to the solution?

Adding more PbS(s) will not have any effect on the system as the equilibrium is already established with the given concentration of Pb 2+ and S 2 − . Therefore, the addition of PbS(s) will not shift the equilibrium in any direction.
