Question

The example of colligative property is

• A. boiling point
• B. osmosis
• C. freezing point
• D. osmotic pressure

Answer 1

Answer: (D)

Colligative properties are properties of solution which depend on the number of particles present in solution.
Elevation in boiling point, pressure, depression in vapour pressure, and depression in freezing point are colligative properties.
Osmotic pressure is proportional to the concentration of solute particles ci and is, therefore, a colligative property.
