Final answer:
A supersaturated solution is one where the solute concentration exceeds the solubility of the solute. Such solutions are typically created by heating a solvent, dissolving more solute, then cooling, and are not stable.option a)) True
Step-by-step explanation:
A solution with a solute concentration greater than the solubility is indeed called a supersaturated solution. This occurs under special circumstances, typically by heating a solvent and dissolving more solute than would typically dissolve at ordinary temperatures.
When such a solution is cooled carefully, it may temporarily contain more solute than it can stably hold at that temperature, thus being supersaturated. However, supersaturated solutions are metastable; they are prone to reverting to a lower, more stable concentration, often by the precipitation or crystallization of the excess solute. For example, when a seed crystal is added to a supersaturated solution, it can cause the excess solute to rapidly recrystallize.
