The term "freezing point depression" refers to a condition where the freezing point of a liquid is lowered by the presence of an additive. This is observed in all solutions, and the freezing point is determined by the amount of solute particles dissolved in the solvent.
At the freezing point of that particular solution, the chemical potential of the solution at liquid state and solid state will be equal. Solute particles are able to dissolve only in a liquid solvent. Conversely, when the solvent is in a solid state, solute particles cannot be dissolved. Following the same logic, adding a solute to the solvent will reduce the chemical potential of the solution and consequently, also its freezing point.
