Minnesota Roads in the Winter

Minnesota Roads in the Winter

Author: Beth Barsness

Students will evaluate different ionic substances for their effect on the freezing point of water.  They will use the information obtained to determine the best “deicer” for use on Minnesota roads in the winter.

This is a lab experience that pulls together many of the known properties of solutions, including freezing point temperature change, exothermic/endothermic solvation processes, effect of ions in solution, and concentration expressed as molality.

Length of time needed:  2-3 class periods (60 minutes each)
