Solubility of salts in water - comparison with the solubili-ty of gases in water

In contrast to gases, the higher the temperature of the water, the better salts dissolve in it. By supercooling them, metastabile supersaturated solutions can be prepared which exhibit a higher concentration than that corresponding to the thermodynamic equilibrium quantity at a given temperature.

In this experiment students prepare saturated (and supersatured) solutions at different temperatures and investigate the properties of this solutions.
