What happens to a saturated solution of sugar in water when the temperature of the solution is suddenly lowered by 10°C?

Clean crystals of sugar will be noticed in the cup.


Dillution of a certain substance in a certain solvent depends on temperature. Specifically, dillution is increased when temperature increases. Since the solution was saturated, it couldn't dissolve more sugar. Once the temperature drops, the water has a new saturation point (lower grams of sugar) and now discharges the sugar from its mass.


This is actually a method used for cleaning solid organic compounds from impurities called recrystallization.
