The solubility of a salt is 36 g per 100 mL of water at room temperature. A solution is prepared by dissolving 40 g in 100 mL of water at 80 °C. The solution is then slowly cooled down to room temperature with precipitation. The solution is
supersaturated at 80 °C
saturated at room temp. after precipitation completes
unsaturated at room temp. before precipitation occurs.
supersaturated at room temp. after precipitation completes.
