The reason is that the more massive bound deuterons have less zero-point energy than do the less massive bound protons, for reasons easily understood from basic quantum mechanics. That means their energy can drop more as they freeze into a more rigid pattern. Sure enough, Wikipedia says that heavy water has a freezing point of 3.8°C. My guess ...

Delta T is the freezing point depression, Kf is the freezing point depression constant (in this case it's 20 C/m), and m is the molality of the solution. In this lab the first thing we need to do it determine the delta T. This can be done by using the following equation: Delta T= T1(pure liquid) - T2 (mixed liquid).

To find the temperature change elevation of a solvent by a solute, use the freezing point depression equation: ΔT = iK f m where ΔT = Change in temperature in °C i = van 't Hoff factor K f = molal freezing point depression constant or cryoscopic constant in °C kg/mol m = molality of the solute in mol solute/kg solvent.The freezing point is the temperature at which the substance phase changes from liquid to solid. Oppositely, the melting point happens with the change of the solid phase to the liquid phase at the same temperature. For example, the freezing point of pure water is at 0.002519 ℃ at atmospheric pressure (101,325 Pa) (Liangjun et al. 2019 ).The average freezing point of these samples was --0.540 ° C.
