colligative property solution

Colligative properties are features of a solution that depend solely on the number of dissolved particles, not their type. When a substance dissolves in a liquid, it changes properties like boiling point, freezing point, vapor pressure, and osmotic pressure. For example, adding salt to water raises its boiling point and lowers its freezing point because more particles are present, affecting how the liquid behaves. These changes are proportional to the amount of dissolved particles, making colligative properties useful for understanding solutions and calculating concentrations in chemistry.
