Which statement best defines the common-ion effect in aqueous solutions?
(a) The shift in a dissolution equilibrium that results from the addition of any soluble salt, regardless of whether it shares an ion with the solid.
(b) The decrease in the solubility of an ionic solid when the solution already contains one of the ions produced by that solid.
(c) The increase in the solubility of an ionic solid when the solution already contains one of the ions produced by that solid.
(d) The change in the pH of a buffer solution that results from dilution with distilled water.
