Chemistry: Freezing Point Depression

Formulas for freezing point depression

\Delta T = K_{f}  m

BrightStorm Freezing point depression


Now let’s apply this conceot to earth science and calculate the freezing point of sea water.  Assume that seawater has a salinity of 35 ppt. convert ppt to molality and calculate freezing point depression  then determine the actual freezing point of sea water.


Q: what is the coldest temperature of ocean water?
