Product Details

Why do road crews spread salt on the roads in the winter? Is one salt better than another to melt snow and ice? Discuss colligative properties as students determine the effect of dissolved impurities on the freezing point of a substance and compare the effect of different additives on the freezing point. Teacher Notes and reproducible student handouts included. All necessary chemicals and specialized equipment are provided in the kit.

Complete for 30 students working in pairs.
