Colligative Properties Experiment 15: Colligative Properties Postlab 1. When the stems of cut flowers are held in concentrated NaCl (aq), the flowers wilt. Explain the basis of this phenomenon. Is this an isotonic, hypotonic or hypertonic solution? 2. Given two NaCl(aq) solutions at the same temperature; (1) saturated solution with excess NaCl(s) remaining at the bottom of the container and (2) an unsaturated solution with all NaCl dissolved in solution. a. Above which solution is the vapor pressure of water greater? Explain. b. Which of these solutions has the higher boiling point? Explain

We use colligative properties when we salt roads and sidewalks to prevent the formation of ice. The most common salt used is sodium chloride. However, at the same molality, other salts, such as barium chloride, would cause a larger decrease in the freezing point temperature. What are two other salts that can cause a similar freezing point change. Why is this? (3-4 Sentences)
