I believe the solution that contains the maximum amount of solute present within it at a given temperature, would be referred to as saturated. No more solute can dissolve or be mixed within the solvent and have it dissolved at that temperature.
Saturated solution is defined as the solution in which no more solute particles can be dissolved in the solvent and thus contain maximum solute at a given temperature.
Unsaturated solution is defined as the solution in which more solute particles can be dissolved in the solvent at any particular temperature.
Supersaturated solution is defined as the solution in which more amount of solute particles is present than the solvent particles and thus the solute is in precipitated form.
