Text Solution
Verified by ExpertsB
(i) Electro osmosis: When movement of colloidal particles is prevented by some suitable means (porous diaphragm or semi permeable membranes), it is observed that the D.M. begins to move in an electric field. This phenomenon is termed electrosmosis.
(ii) Solvent molecules pass through semi-permeable membrane towards solvent side is termed as reverse osmosis.
(iii) When an electric potential is applied across two platinum electrodes dipping in a colloidal solution, the colloidal particles move towards move towards one or the other electrode. The movement of colloidal particles under an applied electric potential is called electrophoresis.
(iv) Solvent molecules pass through semipermeable membrane towards the solution side is termed as osmosis.
