Solubility product constant

Solubility product constants are values to describe the saturation of ionic compounds with low solubility. A saturated solution is when there is a dynamic equilibrium between the solute dissolved, the dissociated ions, the undissolved and the compound. The general equation is MxAy (s) - - > x My + (aq) + y Ax - (aq) where the solubility product constant expression is Kc = [My+]x[Ax-]y.
