ionic equilibrium

Ionic equilibrium is an equilibrium state existing in solutions of electrolytes. Strong acids and bases are completely dissociated into ions when in aqueous solutions, but weak acids and bases are only partly dissociated. Electrolyte, AB, when placed in solution, into A+ and B-. [A+][B-]/[AB], where [ ] indicates activities, is a constant, called the equilibrium constant.
