In thermodynamics, the cryoscopic constant, Kf, relates molality to freezing point depression (which is a colligative property). It is the ratio of the latter to the former: • i is the van ‘t Hoff factor, the number of particles the solute splits into or forms when dissolved. • b is the molality of the solution. Web28 de ago. de 2024 · In Equation 2.2.1 the freezing point depression of a non-ionic solution is described. Where ∆T f is the change in the initial and final temperature of the pure solvent, K f is the freezing point depression constant for the pure solvent, and m (moles solute/kg solvent) is the molality of the solution.
