Question
Chemistry Question on Colligative Properties
Which of the following is a non-colligative property?
A
Elevation in boiling point
B
Osmotic pressure
C
Optical activity
D
Depression in freezing point
Answer
Optical activity
Explanation
Solution
The properties of the solutions which depend only on the number of solute particles, are called colligative properties, eg, relative lowering of vapour pressure, elevation in boiling point, depression in freezing point, osmotic pressure. While optical activity is not a colligative property.
