Learning Goal:
To learn how to calculate the solubility from Ksp and vice versa.
Consider the following equilibrium between a solid salt and its
dissolved form (ions) in a saturated solution:
CaF2 (s) = Ca²+ (aq) + 2F (aq)
At equilibrium, the ion concentrations remain constant because the
rate of dissolution of solid CaF2 equals the rate of the ion
crystallization. The equilibrium constant for the dissolution reaction is
Ksp = [Ca²+][F-12
Ksp is called the solubility product and can be determined
experimentally by measuring the solubility, which is the amount of
compound that dissolves per unit volume of saturated solution.
