Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A : Dissolved substances can be removed from a colloidal solution by diffusion through a parchment paper. Reason R : Particles in a true solution cannot pass through parchment paper but the collodial particles can pass through the parchment paper. In the light of the above statements, choose the correct answ

Step-by-step solution

Colloidal solution particles can be separated using parchment paper. Since Particles (ions or smaller molecules) in a true solution can pass through animal membrane (bladder) or parchment paper or cellophane sheet but not the colloidal particles, the membrane can be used for dialysis.A bag of suitable membrane containing the colloidal solution is suspended in a vessel through which fresh water is continuously flowing (Fig. 5.9). The molecules and ions diffuse through membrane into the outer water and pure colloidal
