Excess PbBr2(s) is placed in water at 25 C. At equilibrium, the solution contains 0.012 M Pb 2+(aq). What is the equilibrium constant for the following reaction? PbBr2(s) --> Pb2+(aq) + 2Br-(aq)
This is just another equilibrium reaction in which the amount of undissolved lead bromide is irrelevant, and, therefore, does not appear in the equilibrium expression.
We are given that at equilibrium,
