Phenomenon that occurs when an electric field is applied to a colloidal solution and electrophoresis is prevented-
a. Reverse osmosis takes place
b. Electroosmosis takes place
c. Dispersion medium begins to move
d. Dispersion medium becomes stationary
The correct choice among the given is -
1. (a, b)
2. (b, c)
3. (c, d)
4. (a, d)
Hint: Electroosmosis process occur in the presence of applied electric potential
The movement of colloidal particles under an applied electric potential is called electrophoresis . When this movementof particles is prevented by some suitable means,it is observed that the dispersion medium begins to move in an electric field. This phenomenonis termed as electroosmosis.
Hence, second option is the correct answer.
