The correct statements with respect to dialysis of colloidal solution are I. Colloidal particles can pass through the membrane. II. Animal bladder can be used as membrane. III. Cellophane is not used as membrane. IV. Ions or small molecules can diffuse through membrane into water.

Options

  1. AI, II only
  2. BII, III only
  3. CIII, IV only
  4. DII, IV only

Correct answer

D. II, IV only

Step-by-step solution

I. Size of colloidal particles are larger than the size of pores present in membrane. Hence, particles of colloidal solution can't pass through membrane. II. Animal bladder can be used as an membrane. III. Cellophane is a thin transparent sheet made of cellulose. It used as an membrane. IV. Ions or small molecules can diffuse through membrane into water. Hence, correct statements are II and IV.
