Are you familiar with Colligative Properties? Do you know that these properties are all around us, in our daily lives? Better yet, do you know how these properties affect us? Take a look on the inside scoop of what goes on to the water you sprinkled salt on while cooking Alfredo pasta, or the reason behind the salting trucks on the highways of New York City in the winter. Take a minute to learn about a fascinating detail of Chemistry! Colligative Properties are Properties resulting from the ratio of the number of solute particles to the number of solvent molecules in a solution. They do not depend on the identity of the solute. They can be applied to solutions. There are not many physical properties of a solution that are colligative properties. When a solute is added to the solvent, the molecules take the space near the surface of the liquid. A common real world application of the Colligative Property is when trucks salt roads in the winter. Since it can be difficult and dangerous to drive on roads that have ice on them during the winter, putting salt on these roads reduces the ice. This impacts people positively so that they can drive without the risk of accidents cause by the road from cold weather. This useful idea works because salt lowers the freezing/melting point of water. This occurs when the salt dissolves into the ice; in the liquid water specifically.
