Please explain Solubility Equilibria and the Solubility Product Constant. Below you will find key questions. 1. Know that the solubility product constant, Ksp, defines the equilibrium constant for the dissolution of an ionic compound into its constituent ions. 2. Calculate the molar solubility of an ionic compound in pure water using the Ksp expression and an ICE table. 3. Know that the solubility of an ionic compound is lower in a solution containing a common ion than in pure water....
