Question

Reezing point of colloidal solutionis lower than true solution at sameconcentration of a solute.

Answer 1

Colligative Properties-

The particles in colloids are bigger aggregates than those in a true solution. So, the number of particles in a colloid is lesser than a true solution of the same concentration. The values of colligative properties (osmotic pressure, lowering of vapour pressure, depression in freezing point, elevation in boiling point) are of small order as compared to values shown by true solution at same concentration.
