What equilibrium constant applies to an aqueous solution of a slightly dissociated ionic compound?

Question

Quizplus · Accepted Answer

A slightly dissociated ionic compound is a sparingly soluble salt, and the equilibrium constant that applies to this situation is the solubility product equilibrium constant, Ksp. Ksp is a constant that represents the dissolution and precipitation of a sparingly soluble salt in water. Keq is a general equilibrium constant that describes the equilibrium of a chemical reaction in a homogeneous phase, Ki is the ionization equilibrium constant that describes the degree of ionization of a weak electrolyte, and Kw is the ion product constant for water, which is the product of the concentrations of dissociated hydrogen and hydroxide ions in water.
