How is Ksp related to molarity?

K_(sp) is related to molarity as follows:

For a saturated solution where an ionic solid such as silver chloride is in equilibria with its aqueous ions we can write:

AgCl_((s))rightleftharpoonsAg_((aq))^(+)+Cl_((aq))^(-)

For which K_(sp)=[Ag_((aq))^+][Cl_((aq))^-]

This relationship is temperature dependent.
