What is freezing point depression in chemistry and how does it affect the properties of a solution?

Freezing point depression in chemistry is the phenomenon where the freezing point of a solution is lower than that of the pure solvent. This occurs when a solute is added to a solvent, disrupting the solvent's ability to form solid crystals. As a result, the solution needs to be cooled to a lower temperature in order to freeze. This affects the properties of the solution by changing its physical state and altering its freezing behavior.
