Question

1. What is freezing point depression? Why is the freezing point ofa solution lower than that of a pure solvent?

2. How does the freezing point depression depend on the molality ofa solution?

3. What is meant by the freezing point depression constant,Kf?

4. What is the freezing point of a solution made by dissolving 3 gof glucose in 100 mL of water (assume density of 1.0 g/mL), if theKf for water is 1.86 C/m?

5. Calculate the freezing point of a 0.1 m glucose solution. If thesolution is 0.1 m of sucrose instead of glucose, what is thefreezing point? Why the freezing points of the two solutions arethe same?

Thanks in advance!
