When electric field is applied to colloidal solution the colloidal particles moves towars electrodes.
The movement of colloidal particles towards a particular electrode under the influence of an electrical field is called electrophoresis.

The direction of movement of colloidal particles towards a particular electrode is governed by the nature of the charge on them. If the colloidal particles carry a positive charge, then they move towards the cathode when subjected to an electrical field, while negatively charged colloidal particles move towards the anode.

An important application of electrophoresis is in sewage disposal.

Answer:

When electric current is passed through a colloidal sol, the colloidal particles move towards oppositely charged electrode, where they lose their charge and are coagulated. The process is known as electrophoresis.
