What is the best way to make a supersaturated solution?

A solution of a chemical compound in a liquid will become supersaturated when the temperature of the saturated solution is changed. In most cases solubility decreases with decreasing temperature; in such cases the excess of solute will rapidly separate from the solution as crystals or an amorphous powder. In a few cases the opposite effect occurs. The example of sodium sulfate in water is well-known and this was why it was used in early studies of solubility. WebThe solubility of salt A in 100 mg of water is 25 grams at 25°C. A solution is prepared by adding 30 milligrams of salt A in 100 grams of water at 25°C.
