Solubility and Solubility Product

The dissolving of a sparingly soluble solute can be represented by an equilibrium equation:


As this is an equilibrium, we can write an equilibrium expression, called the Solubility Product:


The smaller the Solubility Product, the less soluble a solute is.

Solubility is usually expressed in one of two units: grams per litre (g L-1); or moles per litre (mol L-1).

We can use the solubility of a solute to calculate the Solubility Product, and use the the Solubility Product to calculate the solubility of a solute. Once we master these two skills, we have a good understanding of solubility.
