Common-ion effect the presence of either ca 2+ (aq) or f – (aq) in a solution reduces the solubility of caf 2, shifting the solubility equilibrium of caf 2 to the left: this reduction in solubility is another application of the common-ion effect.
The common ion effect is the phenomenon in which the addition of an ion common to two solutes causes precipitation or reduces ionization you know le chatelier's principle, which states that a reaction stays in equilibrium unless acted on by an outside force then the reaction will shift to accommodate the force and re-establish equilibrium. The common-ion effect is used to describe the effect on an equilibrium involving a substance that adds an ion that is a part of the equilibrium.
