Question

Identify the incorrect statement:

• A. Values of colligative properties of colloidal solutions are of small order compared to values of true solutions.
• B. Tyndall effect is observed only when the diameter of the dispersed particles is not much smaller than the wavelength of incident light.
• C. Colour of colloidal solution depends on the wavelength of light scattered by the dispersed particles.
• D. Brownian movement is due to balanced bombardment of molecules of the dispersion medium on colloidal particles.

Hint:

Brownian movement arises from random molecular collisions.

Answer 1

The Correct Option is D

Brownian movement occurs due to the unbalanced bombardment of molecules of the dispersion medium on colloidal particles, leading to their random motion.
