Define: (a) Solute (b) Solvent (c) Solution (d) Saturated solutions (e) Unsaturated solutions

(a) Solute : A solute is a substance that dissolves in a medium which can be water or any other substance. Solute is in smaller quantity in a solution. 

(b) Solvent : A solvent is a medium in which a solute dissolves. It is in large quantity in a solution. Water is the most common solvent. The other solvents are alcohol, carbon tetrachloride etc.

 (c) Solution : A solution is a homogeneous uniform mixture formed by a solute and a solvent. 

(d) Saturated solution : When a solution cannot dissolve any more of solute at a given temperature, it is called saturated solution. 

(e) Unsaturated solution : A solution that can take up more of the solute at a given temperature, is said to be an unsaturated solution.
