Final answer:
An unsaturated solution is a solution that has the capacity to hold additional solute at a given temperature.
Step-by-step explanation:
A solution that has the capacity to hold additional solute at a given temperature is called an unsaturated solution. An unsaturated solution is one in which the solute's concentration is less than its solubility. This means that more solute can be added to the solution and it will continue to dissolve.
