There are many examples of water having impurities of sodium chloride such as sea water and water on roads that have been salted. Pure solid water (ice) melts at 0 ºC. Sodium chloride melts at 800 ºC. Do you think ice with impurities of sodium chloride would melt below 0 ºC, above 0 ºC, or at 0 ºC? Explain your reasoning based on what you know about melting points in a lab.
