Raoult's cryoscopic constant

Raoult's cryoscopic constant is a measure of how much the freezing point of a solvent decreases when a solute is added. Each solvent has its own cryoscopic constant, which indicates the freezing point depression per molal concentration of solute particles. This principle is used in various applications, such as determining the molecular weight of substances and understanding how different solutions behave at low temperatures. Essentially, it helps predict how much colder a solution will become compared to the pure solvent, providing insight into the properties of mixtures and solutions in chemistry.
