Question

Statement-1:All colloidal dispersions give very low osmotic pressure and show very small freezing point depression or boiling point elevation.
Statement-2:Tyndall effect is due to scattering of light from the surface of colloidal particles.
A. STATEMENT -1 is true, STATEMENT-2 is true and STATEMENT-2 is correct explanation for STATEMENT-1
B. STATEMENT -1 is true, STATEMENT-2 is true and STATEMENT-2 is not correct explanation for STATEMENT-2
C. STATEMENT-1 is true, STATEMENT-2 is false
D. STATEMENT-1 is false, STATEMENT-2 is true

Answer 1

Correct Answer - B
Colloidal particles have high molar mass, so their mole fraction is very less causing low colligative properties.
