Learn why salt is added to icy road surfacesSalt and Icy Roads

On those cold winter mornings, why do we add salt to icy road surfaces? Find out by watching this snow and ice chemistry video. Directly heating the roads isn’t an easy option so adding salt (sodium chloride) is a much better idea, it manages to lower the freezing point considerably. Calcium chloride works in much the same way but you can use less and have the same results as the sodium chloride. The video also goes on to explain the differences between ice and snow as well as the shape of ice crystals. Enjoy this fun science video for kids.
