MCQ
The colligative properties of a solution depend on 
  • ✓
    The relative number of solute particles present in it
  • B
    The chemical nature of the solute particle present in it.
  • C
    The size of the container used
  • D
    None of these
✓

Answer

Correct option: A.
The relative number of solute particles present in it
a
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 vapour pressure of the solvent.

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

($iii$) Depression in freezing point of solvent.

($iv$) Osmotic pressure.
