1. Which of the following is NOT a colligative property?
Boiling point elevation
Vapor pressure lowering
Density
Freezing point depression
2. Adding salt to water causes its boiling point to:
Increase
Decrease
Remain the same
Fluctuate rapidly
3. Colligative properties depend only on the of solute particles in a solution, not on their identity.
4. The addition of a non-volatile solute to a solvent will cause the vapor pressure of the solvent to .
5. Freezing point depression is observed when a solute is added to a solvent, lowering the freezing point of the solution.
True
False
6. Osmotic pressure is the pressure that must be applied to a solution to prevent the inward flow of water across a semipermeable membrane.
True
False
7. Explain why salt is often spread on icy roads in winter.
8. Describe the phenomenon of boiling point elevation.
