Question

Colligative properties of the solution depend on:

• A. nature of solute
• B. nature of solvent
• C. number of particles present in the solution
• D. number of moles of solvent only

Answer 1

The correct option is C number of particles present in the solution

Colligative properties: Those physical properties of a solution which depend upon the number of particles in a given volume of the solution or the mole fraction of the solute are called colligative properties.
The following four properties are colligative properties :

(i)Lowering of the vapour pressure of the solvent.

(ii)Elevation in the boiling point of the solvent.

(iii)Depression in freezing point of the solvent.

(iv)Osmotic pressure.
