Consider a beaker containing a saturated solution of CaF2 in equilibrium with
undissolved CaF: (s).
(a) If solid CaCla is added to this solution, will the amount of solid CaF2 at the bottom
of the beaker increase, decrease or remain the same?
(b) Will the concentration of Ca+ ions in solution increase or decrease?
