(a) A solute is a substance that dissolves in a solvent to form a solution. It is in a smaller quantity in a solution.
(b) A solvent is a medium in which a substance is dissolved to form a solution. It is usually a liquid and is present in a large quantity in a solution.
(c) A solution is a uniform homogeneous mixture formed by dissolving a solute in a solvent. A solution can be of two types, namely saturated and unsaturated.
(d) A solution is said to be saturated when it cannot dissolve any more of the solute at a given temperature.
(e) A solution that can dissolve more of the solute at a given temperature, is said to be an unsaturated solution.
