Question

Colligative properties are exhibited by dilute solutions.

1. What do you mean by colligative properties?

2. Which are the four colligative properties?

Answer 1

1. Colligative properties are those properties of dilute solutions of non-volatile solutes whose value depend upon the number of solute particles irrespective of their nature relative to the total number of particles present in the solution.

2. The four colligative properties

• Relative lowering of vapour pressure 
• Elevation of boiling point 
• Depression of freezing point 
• Osmotic pressure
