Define: (i) Hypertonic solution; (ii) Hypotonic solution; (iii) Isotonic solution.

(i) Hypertonic Solution: A solution having higher concentration of solute with respect to another solution, is called hypertonic solution.

(ii) Hypotonic Solution: A solution having higher concentration of solvent with respect to another solution, is called hypotonic solution.

(iii) Isotonic Solution: A solution that have exactly the same water concentration with respect to another solution, is called isotonic solution.
