STATEMENT-1 : 0.1 M solution of Na(2)SO(...

STATEMENT-1 : 0.1 M solution of `Na_(2)SO_(4)` has greater osmotic pressure than 0.1 M solution of urea at same temperature.
and
STATEMENT-2 : The value of van't Hoff factor for `Na_(2)SO_(4)` is less than urea.

Text Solution

Verified by Experts

The correct Answer is:
Because colloidal solutions being bigger aggregate of a large number of molecule, the effective number of particles in colloidal solution is relative much smaller.
