Answer:

Saturated solution

Explanation:

Saturated solution is the solution in which no more solute can be dissolved at a particular temperature.

A amount of the solute, potassium nitrate is dissolved at elevated temperature and on cooling, it precipitates. It means that the solution is saturated at that temperature. <u>Precipitation of the solute at lower temperature indicates that the solution is saturated solution.</u>
