    Common Ion Solubility

    I am getting confused on this concept. Everywhere says that Common Ions decrease solubility. Yet in this problem, Ksp of PbCl2 is 1.6x10-5. What is the solubility of PbCl2 in .01 M KCl? The solubility is .16 M. So wouldn't that mean that common ions make the solubility increase?
