E)none of the above

Quizplus · Accepted Answer

A saturated solution is one in which the maximum amount of solute has been dissolved in a solvent at a given temperature and pressure. If there is visible solute left in the bottom of the beaker after heating and cooling, it means that the solution was already saturated and could not dissolve any more. This distinguishes it from an unsaturated solution, in which more solute could still be dissolved, and a supersaturated solution, in which excess solute has been dissolved at a higher temperature but may precipitate out upon cooling. "Thermally saturated" is not a commonly used term in chemistry.
