what is the molal freezing point constant
This phenomenon is referred to as freezing point depression. The mathematical equation describing freezing point depression is: Î´T = (Kf)(m). Î´T represents the freezing point depression: Î´T = Tfo-Tf. Tfo is the freezing point of the pure solvent. Tf is the freezing point of the solution. Kf is the molal freezing point depression constant, which has a characteristic value for a given solvent. The units of Kf are given in oC/m. is the molality of the solution.
