- B(A) - (II), (B) - (IV), (C) - (I), (D) - (III)
- C(A) - (I), (B) - (II), (C) - (IV), (D) - (III)
- D(A) - (III), (B) - (IV), (C) - (II), (D) - (I)
Correct answer
D. (A) - (III), (B) - (IV), (C) - (II), (D) - (I)
Step-by-step solution
Brownian motion is the continuous random zig-zag movement of colloidal particles due to unequal bombardment by the molecules of the dispersion medium. Thus, (A) (III). Tyndall effect is the scattering of light by colloidal particles, making the path of light visible. Thus, (B) (IV). Electrophoresis is the movement of colloidal particles towards oppositely charged electrodes under the influence of an applied electric field. Thus, (C) (II). Dialysis is the process of removing dissolved impurities from a colloidal sol
