In this lab experience, students carry out an investigation examining road deicers. They combine their data with cost information to make a recommendation about which material should be used. Students should come to understand that the more species a compound dissociates into, the greater the effect it has on the melting point. Calcium chloride is found to be the most effective road deicer. However, at twice the price of sodium chloride students might not consider it to be cost effective.
