A chemist prepares a solution by heating water and adding solid KCl until no more would dissolve. When the clear solution is capped and set aside, after several hours it becomes cloudy and some solid has settled at the bottom of the flask. Which statement best describes what happened?
As the solution cooled, evaporation of water increased the KCl concentration beyond its solubility.
Water molecules, trapped with the KCl crystals, were released after heating.
At lower temperatures the solubility of KCl decreased and recrystallization occurred.
At increased temperatures the solubility of KCl increased and remained too high after cooling.
