Question

The total number of colligative properties are:

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is D 4

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.
