Question
To make rock candy, sugar is dissolved in hot water until no more can dissolve, then the solution is allowed to cool. A stick is placed in the sugar solution and crystals form on the stick. Describes what happens in terms of unsaturation, saturation, and supersaturation. The hot solution is supersaturated and the cooled solution is unsaturated. The hot solution is supersaturated and the cooled solution is saturated. The hot solution is unsaturated and the cooled solution is saturated. The hot solution is saturated and the cooled solution is supersaturated. The hot solution is saturated and the cooled solution is unsaturated.Explanation / Answer
Q1.
Initially, the solution is hot, so it will dissolve plenty of sugar, then we cool it down. As we cool it down, solubility of Candy decreases, until it becomes saturated, and evnetually supersaturated solution, therefore, solids must form.
Therefore
hot solution --> saturated
cooled solution --> supersaturated
