Solubility Product Constants at 25 Degrees Celsius

Solubility Product Constants at 25 Degrees Celsius The solubility product works as follows: In a water solution at equilibrium with a slightly soluble ionic compound, the product of the concentration of the ions, raised to the power of its coefficient in the solubility equation, is a constant. The solubility constant, Ksp, has a fixed value at a given temperature and is independent of the concentration of the individual ions. Here are values of Ksp for several slightly soluble ionic solids: Actetates AgC2H3O2 2 x 10-3 Bromides AgBr 5 x 10-13PbBr2 5 x 10-6 Carbonates BaCO3 2 x 10-9CaCO3 5 x 10-9MgCO3 2 x 10-8 Chlorides AgCl 1.6 x 10-10Hg2Cl2 1 x 10-18PbCl2 1.7 x 10-5 Chromates Ag2CrO4 2 x 10-12BaCrO4 2 x 10-10PbCrO4 1 x 10-16SrCrO4 4 x 10-5 Fluorides BaF2 2 x 10-6CaF2 2 x 10-10PbF2 4 x 10-8 Hydroxides Al(OH)3 5 x 10-33Cr(OH)3 4 x 10-38Fe(OH)2 1 x 10-15Fe(OH)3 5 x 10-38Mg(OH)2 1 x 10-11Zn(OH)2 5 x 10-17 Iodides AgI 1 x 10-16PbI2 1 x 10-8 Sulfates BaSO4 1.4 x 10-9CaSO4 3 x 10-5PbSO4 1 x 10-8 Sulfides Ag2S 1 x 10-49CdS 1 x 10-26CoS 1 x 10-20CuS 1 x 10-35FeS 1 x 10-17HgS 1 x 10-52MnS 1 x 10-15NiS 1 x 10-19PbS 1 x 10-27ZnS 1 x 10-20
