Question

The colligative property of a solution depends on

• A. the total number of solute particles relative to solvent/solution
• B. the size of the particle
• C. the shape and charge of the particle
• D. none of the above

Answer 1

The correct option is A the total number of solute particles relative to solvent/solution

The properties of the solution that are dependent only on the total number of solute particles relative to solvent/solution​ is called colligative property.

They are not dependent on the nature of particle i.e., shape, size, charge, etc. ​
There are ​4 colligative properties of solution.
1. Relative lowering ​of vapour pressure​
2. Elevation in boiling point​
3. Depression in​ freezing point​
4. Osmotic pressure
