Statement I: Except osmotic pressure, all other colligative properties depend on the nature of solvent.
Statement II: Colligative properties are intensive properties.
Answer & explanation
Correct answer: option 4
The correct answer is option 4. Statement I is INCORRECT, but Statement II is CORRECT.
Statement I: Except osmotic pressure, all other colligative properties depend on the nature of solvent.
This statement is incorrect. All colligative properties depend only on the number of solute particles in the solution, not on the identity of the solute particles. This is because colligative properties are determined by the number of particles in solution that can interact with the solvent molecules. The identity of the solute particles does not affect the number of particles that can interact with the solvent molecules.
Statement II: Colligative properties are intensive properties.
This statement is correct. Colligative properties are intensive properties, which means that they do not depend on the amount of the solution. This is because colligative properties are determined by the number of particles in solution, and the number of particles in solution does not depend on the amount of the solution.
