Colligative properties of solutions, such as boiling point elevation and freezing point depression, have practical applications in various real-world scenarios. These properties depend on the concentration of solute particles in a solution, regardless of their nature. Here's an example of a situation where these properties are applied:De-icing roads and sidewalks during winter: In colder regions, ice and snow can accumulate on roads and sidewalks, making them slippery and dangerous for pedestrians and vehicles. To prevent accidents and ensure safe transportation, it is essential to remove ice and maintain a clear path. One common method to achieve this is by using salt sodium chloride or other chemicals to lower the freezing point of water.When salt is spread on icy roads, it dissolves in the thin layer of liquid water present on the ice surface, forming a saltwater solution. Due to the presence of dissolved salt particles, the freezing point of this solution is lower than that of pure water. As a result, the ice melts at a lower temperature, and the liquid water does not freeze again as long as the temperature remains above the new, lower freezing point.This application of freezing point depression helps to keep roads and sidewalks ice-free and safe for use during winter months. Similarly, other chemicals like calcium chloride and magnesium chloride can also be used for de-icing purposes, as they exhibit the same colligative property effect.In summary, the concepts of colligative properties, such as boiling point elevation and freezing point depression, have practical applications in real-world scenarios like de-icing roads and sidewalks during winter. These properties help to maintain safety and prevent accidents caused by icy surfaces.
