A solubility equilibrium exists when a chemical compound in the solid state is in chemical equilibrium with a solution containing the compound. This type of equilibrium is an example of dynamic equilibrium in that some individual molecules migrate between the solid and solution phases such that the rates of dissolution and precipitation are equal to one another. When equilibrium is established and the solid has not all dissolved, the solution is said to be saturated… WebSolubility product constant is just a dressed up equilibrium constant. It's the equilibrium constant. For a dissolution reaction, which makes since, right? Because we've got the word solubility in Ksp, right, and that goes along with a dissolution reaction. So there are many types of ionic compounds which are highly solubable in water.
