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)
