A solution is formed at room temperature by vigorously dissolving enough of the solid solute so that some solid remains at the bottom of the solution.Which statement below is TRUE?
A) The solution is considered unsaturated.
B) The solution is considered supersaturated.
C) The solution is considered saturated.
D) The solution would be considered unsaturated if it were cooled a bit to increase the solubility of the solid.
E) None of the above is true.

Quizplus · Accepted Answer

If some solid remains at the bottom of the solution after vigorous dissolving, then the solution is at saturation point. This means that the maximum amount of solute that can be dissolved at that temperature has been reached. If there is less solute than what can be dissolved, the solution would be unsaturated, and if there is more solute than the maximum that can be dissolved, it would be supersaturated. Cooling the solution would not change the saturation level unless the solubility of the solid decreases as the temperature decreases.
