Correct Option 4) Colloids move towards the opposite electrode of their charge

Electrophoresis is a method used to separate and analyze colloidal particles based on their charge and size. When an electric field is applied to a colloidal solution, the charged particles move towards the electrode of the opposite charge. The direction of movement depends on the charge of the particles.

Positively charged colloids move towards the cathode, while negatively charged colloids move towards the anode. Neutral colloids do not have a charge and do not move under the influence of an electric field.
