A solution that contains less solute than can be dissolved in it at a given temperature is called a(n) _________ solution.

A solution that contains less solute than can be dissolved at a given temperature is termed an unsaturated solution. In an unsaturated solution, there is still capacity for more solute to be dissolved, which means that if additional solute is added, it will dissolve until the solution reaches a point of saturation.

This definition highlights the dynamics of solubility and the limits of how much solute can be incorporated into a solvent at any temperature. In contrast, a saturated solution is one where the maximum amount of solute has been dissolved, resulting in any additional solute remaining undissolved. A supersaturated solution involves more solute than can be dissolved at that temperature under normal conditions, which is a unique and often unstable state. Hypersaturated is not a standard term used in this context and doesn’t apply to the classification of solutions.
