movement of dispersion medium under the influence of

Movement of dispersion medium under the influence of electric field is known as

A. electrodialysis

B. electrophoresis

C. electroosmosis

D. cataphoresis

Answer : electroosmosis

Solution :
When movement of particles ( electrophoresis ) is prevented by some suitable means, it is observed that the dispersion medium begins to move in an electric field. This phenomenon is termed as electroosmosis.
