± Introduction to Solubility and the Solubility Product
Constant
Learning Goal:
To learn how to calculate the solubility from Kspand
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−]2
Ksp is called the solubility product and can be...
