What happens when electric ‘ield is applied to colloidal solution?

NEETprep Answer: 
 
When electric potential is applied to colloidal solution, the colloidal particle move towards one or other electrode. Pusilively charged particles move towards the cathode while negatively charged particles tnuve towards the anode.

The movement of colloidal particles under an applied electric potential is called electrophoresis. When electrophoresis is prevented by some means, then the dispersion medium begins to movein an electric field. This phenomenonis termed as electroosmosis.
