🤓 Based on our data, we think this question is relevant for Professor Bennett's class at ECU.
We are being asked to determine the amount of solid CaF2 after the addition of solid CaCl2 to a saturated CaF2 solution.
We will determine if the amount of solid CaF2 increased, decreased or remain the same.
We are dealing with a Ksp problem that has a common ion effect.
Common ion effect is the effect of the addition of common ions to the equilibrium of a solution.
Consider a beaker containing a saturated solution of CaF2 in equilibrium with undissolved CaF2(s). Solid CaCl2 is then added to the solution.
Will the amount of solid CaF2 at the bottom of the beaker increase, decrease, or remain the same?
