b) rite the corresponding equilibrium constant expression. c) What specific name is given to the equilibrium constant expression for relatively insoluble salts? d) Explain why the solid lead(II) bromide is not used in this equilibrium constant expression. 2. When an ionic compound dissolves in water, the individual ions first leave the crystal lattice and then each ion becomes surrounded by a cluster of polar water molecules. What is the sign of the entropy change for each of these two steps in the dissolving process?

Learning Goal: To learn how to calculate the solubility from Kspand vice versa. Consider the following equilibrium between a solid salt and its dissolved form (ions) in a saturated solution: CaF2(s)⇌Ca2+(aq)+2F−(aq) At equilibrium, the ion concentrations remain constant because the rate of dissolution of solid CaF2 equals the rate of the ion crystallization. The equilibrium constant for the dissolution reaction is Ksp=[Ca2+][F−]2 Ksp is called the solubility product and can be determined experimentally by measuring thesolubility, which is the amount...
