Solubility in crystallization
WebA solute/solvent system with low solubility at low temperature, but with solubility being a strongly increasing function of temperature, is suitable for cooling recrystallization. A large amount of solute can be dissolved at high temperature and due to lower solubility at low temperature, controlled cooling can initiate recrystallization.
