Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. Colligative properties depend on the of solute particles in a solution, not on their identity.
2. Adding a solute to a solvent the freezing point of the solvent.
3. The four main colligative properties are vapor pressure lowering, boiling point elevation, freezing point depression, and pressure.
4. When salt is added to water, the vapor pressure of the water .
1. Which of the following is NOT a colligative property?
Boiling point elevation
Freezing point depression
Density
Osmotic pressure
2. Which of the following explains why roads are salted in winter?
Boiling point elevation
Freezing point depression
Vapor pressure lowering
Osmotic pressure
1. The addition of a non-volatile solute to a solvent increases its boiling point.
True
False
2. 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
1. Define colligative properties and give two examples of their real-world applications.
2. Explain why adding antifreeze to a car's radiator helps prevent both freezing in winter and boiling in summer.
3. Based on your understanding of colligative properties and the provided illustration, describe how the presence of dissolved salt affects the vapor pressure of water. Why does this happen?
