Chemistry Question on Solutions
Which among the following is a non-colligative property?
A
Elevation in boiling point
B
Osmotic pressure
C
Refractive index
D
Lowering of vapour pressure
Answer
Refractive index
Explanation
Solution
The properties of a dilute solution which depends only upon the number of particles present in a solution and their concentration are called colligative properties. There are following four colligative properties
[a] relative lowering of vapour pressure
[b] elevation in boiling point of the solvent
[c] depression in freezing point
[d] osmotic pressure
