Answer» Dialysis:- Graham found the crystalline substances like NaCl when dissorded in water can pass through parchment paper or other membranes moval of parchment while colloidal substance like gelatin cannot do so. "The process of separating a crystalloid form a colloid by filtration or diffusion through a membrane is called Dialysis. It is due to the fact that pores of membrane are very small and can only allow the dissolved molecules or ions of the true solution to pass through, but not the bigger sized colloidal particles. The apparatus employed to effect such a separation is known as Dialyser.
