Question

The colligative properties of colloidal solutions are always lower.

• A. True
• B. False

Answer 1

The correct option is A True

• The colligative proprrties of colloidal solutions are always lower.
  
• Colloidal particles being bigger aggregates, the number of particles in a colloidal solution is comparatively small as compared to a true solution.
• Hence, the values of colligative properties (osmotic pressure, lowering in vapour pressure, depression in freezing point and elevation in boiling point) are of small order as compared to values shown by true solutions at same concentrations.
