Correct answer
BColloidal particles in lyophobic sols can be precipitated by electrophoresis.
Step-by-step explanation
Brownian motion of colloidal particle depends on size of particles.
Colloidal medicines are better because of their large surface area.
Electrophoresis is used for ppt. of lyophobic colloid. In electrophoresis precipitation occurs at the electrode which is oppositely charged.
