Question

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

Answer 1

(i) Hypertonic solution: A solution having a higher concentration of solute as compared to another solution is called hypertonic solution . In a hypertonic solution, a cell progressively loses water through exosmosis.

(ii) Hypotonic solutions: A solution having a lesser concentration of solute as compared to another solution is called hypotonic solution . In a hypotonic solution, a cell progressively gains water through endosmosis.

(iii) Isotonic solutions: A solution having a concentration equal to that of another solution is called isotonic solution. In an isotonic solution, a cell neither gains nor loses water.
