An icy-road maintenance worker is trying to melt snow and ice from a recent snowstorm, and usually uses a large-crystal form of sodium chloride. An associate suggests that using Strontium Chloride would be a better solution as the associate mentions that this chemical will lower the freezing point of water more than sodium chloride. With respect to mass (i.e. if the 2 bags are the same weight and the same price) which salt will be more effective in melting the icy roads?
