(B) The process of separating the particles of colloids from those of crystalloids by means of diffusion through a suitable membrane is called $Dialysis$. Colloidal particles cannot pass through a semipermeable membrane (like parchment paper or cellophane),whereas crystalloid particles can pass through it easily. In this process,the impure sol is placed in a bag made of a semipermeable membrane and suspended in a vessel containing distilled water. The crystalloid impurities diffuse out into the water,leaving behind pure colloidal particles.

The process of separating colloidal particles from crystalloid impurities using a semipermeable membrane is known as:
