- DA-I, B-III, C-II, D-IV
Correct answer
B. A-III, B-I, C-IV, D-II
Step-by-step solution
(A) Osmosis: It is a process by which the molecules of a solvent pass from a solution of low concentration to a solution of high concentration through a semi-permeable membrane.
(B) Reverse osmosis: The direction of osmosis can be reversed if a pressure larger than the osmotic pressure is applied to the solution side. Now the pure solvent flows out of the solution through the semi-permeable membrane. This phenomenon is called reverse osmosis.
(C) Electroosmosis: When electrophoresis, i.e., movement of particles is prevented by some suitable means, it is observed that the dispersion medium begins to move in an electric field. This phenomenon is termed electroosmosis.
(D) Electrophoresis: When an electric potential is applied across two platinum electrodes dipping in a colloidal solution, the colloidal particles move towards one or the other electrode. The movement of colloidal particles under an applied electric potential is called electrophoresis.
So the correct matching is A-III, B-I, C-IV, D-II.
