Ionic compounds dissolve to the point where the solution is
saturated and no more solid can dissolve. The concentration of the
saturated solution is termed the solubility of the
substance. In such a saturated solution, equilibrium is established.
Ions will form solid in the same extent as solid dissociate and form
ions. The solubility product constant or solubility
productKsp is a temperature-dependent
constant referring to this stage.
If MxAy dissociate into (cations) M+m
and (anions) A-a The expression for solubility product
will be:
Ksp=[M+m]x [A-a]y
