Solubility and Complex-Ion Equilibria

Abstract Solubility and Complex-Ion Equilibria broadens the previous chapter’s coverage of equilibria to include aqueous systems containing two or more solutes of slightly soluble ionic compounds and the formation of metal complexes in solution. Solubility equilibria which allow quantitative predictions of how much of a compound will dissolve under given conditions are covered. The meaning of the solubility product constant (Ksp) and how to calculate it from molar solubility values is presented. Also discussed is determination of molar solubility from Ksp. Calculations demonstrate how to predict the formation of a precipitate by comparing the ion product or solubility quotient (Q) with Ksp. Formation constants of complex ions and calculations involving complex ion equilibria are explained.
