Question

At same concentration of colloidal and true solution, the colligative properties values of:

• A. colloidal solution is greater than true solution
• B. colloidal solution is equal to true solution
• C. colloidal solution are of small order as compare to those of true solution
  
• D. both (a) and (b)

Answer 1

The correct option is C colloidal solution are of small order as compare to those of true solution


Colligative property is the properties ​of a solution that depend upon the number of solute particles irrespective ​of the identity of solute. ​
Thus, colligative property does not depend on the nature of particle i.e., shape, size, charge, etc.

Colloidal particles ​are bigger aggregates.​ Thus, the number of particles, per unit volume, in a colloidal solution is small as compared to a true solution.​
Therefore, at same concentration​ colligative property values of colloidal solution is lesser than true solution. ​

Hence, option (c) is the correct answer.
