How are supersaturated solutions prepared?

The usual method for creating supersaturated solutions is to dissolve your compound in hot water.

For instance, at 25 degrees Celsius, 210 grams of sugar will dissolve in 100 milliliters of water when added.

Nevertheless, the same volume of water will now dissolve 360 grams of sugar if you heat it to 80 degrees Celsius.

Any situation where more solute is dissolved than possible is called supersaturation. To make a supersaturated solution, make a saturated solution of sugar by adding 360 grams of sugar to 100 mL of water at 80 degrees Celsius. When the water cools back down to 25 degrees, that 360 grams of sugar will still be dissolved even though the water should only dissolve 210 grams of sugar.

Supersaturated solutions are prepared by dissolving a solute in a solvent at an elevated temperature, then allowing the solution to cool slowly without disturbance, or by evaporating the solvent slowly under controlled conditions.
