Solubility
and solubility product are two different terms which must not be confused.
Solubility product is independent of what else is dissolved in solution unlike
the solubility of a substance. The substance’ solubility can be measured from
its solubility product. Below is an
example of a solubility product , Ks which is the equilibrium or balanced constant for the equilibrium
which exists between a slightly soluble salt and its ions in a saturated
solution.
AgCl(s) = Ag+(aq) +
Cl-(aq)
Ks = [Ag+(aq)][Cl-(aq)]
Ks = 1.74 x 10-10 mol2 dm-6
