Question
Define the term Colligative properties
Solution
Colligative Properties :Colligative properties are the properties of the solutions which depend upon the number of solute particles present in the solution irrespective of their nature, relative to the total number of particles present in the solution.
Examples: Relative lowering of vapour pressure of the solvent, depression of freezing point of the solvent, elevation of boiling point of the solvent, osmotic pressure of the solution
