Find freezing point of a solution
WebThis chemistry video tutorial provides a basic introduction into colligative properties such as boiling point elevation, freezing point depression, osmotic p... WebThe freezing point depression, T is proportional to the molality of the solution. The proportionality constant K fp, called the molal freezing-point depression constant, is a property of the solvent. T =(K fp)(m) The table below lists several solvents, their freezing points, and freezing point depression constants.
