Question

Match separation methods in Group I with associated properties in Group II.

• A. A-4, B-2, C-1, D-3
• B. A-3, B-1, C-2, D-4
• C. A-1, B-3, C-2, D-4
• D. A-1, B-2, C-4, D-3

Hint:

Understanding the principle of each separation method, whether it's based on size, density, solubility, or diffusivity, is key to selecting the appropriate technique for a given application.

Answer 1

The Correct Option is D

The separation methods in Group I are matched with their associated properties in Group II as follows:

(1) Centrifugation (A) is based on the density
(1) of the particles, where components with different densities are separated by applying centrifugal force.

(2) Dialysis (B) works on the solubility
(4) of substances in a selective membrane to separate small molecules from larger ones.

(3) Solvent extraction (C) involves separating components based on their solubility and diffusivity
(2) in different solvents.

(4) Ultrafiltration (D) is based on the size
(3) of particles, where larger molecules are retained by the membrane, and smaller molecules pass through.

Conclusion: The correct matching is A-1, B-2, C-4, D-3.
