What is solubility?

Solubility is a chemical property referring to the ability of a given substance, the solute, to dissolve in a solvent. It is measured in terms of the maximum amount of solute that can be dissolved in a given amount of solvent at a specific temperature. The process of dissolving is considered endothermic, as it requires energy to break the bonds in the solute and the solvent. The solubility of a substance depends on the physical and chemical properties of the solute and solvent as well as on temperature, pressure and the pH of the solution.
