Read each question carefully and provide the best answer. Show all your work for calculation problems.
1. Which of the following is NOT a colligative property?
Boiling point elevation
Vapor pressure lowering
Viscosity
Osmotic pressure
2. Adding a non-volatile solute to a solvent will:
Increase its freezing point
Decrease its boiling point
Lower its vapor pressure
Increase its density
1. Colligative properties depend on the of solute particles in a solution, not on their identity.
2. The phenomenon where the freezing point of a solvent is lowered by the addition of a solute is called .
3. Osmotic pressure is directly proportional to the of the solute particles.
1. Explain why salt is spread on icy roads in winter.
2. Describe the concept of boiling point elevation. What factors influence its magnitude?
1. The vapor pressure of a solution is always higher than that of the pure solvent.
True
False
2. Osmosis is the movement of solute particles across a semipermeable membrane.
True
False
1. A solution is prepared by dissolving 25.0 g of glucose (C6H12O6) in 500.0 g of water. Calculate the freezing point depression of the solution. (Kf for water = 1.86 °C/m)
2. What is the boiling point of a solution containing 15.0 g of NaCl in 200.0 g of water? (Kb for water = 0.512 °C/m, assume complete dissociation of NaCl)
