Question:
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 and small molecules can diffuse through membrane into water
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 and small molecules can diffuse through membrane into water
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 and small molecules can diffuse through membrane into water
Show Hint
Dialysis removes impurities (ions) from colloids.
Animal membranes and cellophane are common membranes.

- II, III only
- III, IV only
- II, IV only
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
- Colloidal particles cannot pass through dialysis membrane.
- Animal bladder is a semipermeable membrane – correct.
- Cellophane is used in practice – so statement III is incorrect.
- Ions and small solute molecules do diffuse out – statement IV is correct.
