Why Do We Put Salt On Ice In The Winter. Salt that’s dumped on top of ice relies on the sun or the friction of car tires driving over it to initially melt the ice to a slush that can mix with the salt and then won’t refreeze. The working temperature range isn't the same for all types of salt. Instead of freezing at 32 degrees fahrenheit (0 degrees celsius), salt brings the freezing temperature down to around 0 degrees f (minus 18 degrees c). This phenomenon is called freezing point depression. Melting is endothermic, so it lowers the temperature. Instead it makes water less likely to freeze in a phenomenon called freezing point depression. But how does salt do it? First, it’s important to understand a bit about h 2 o in the winter. Salt doesn’t directly melt ice, nor does it make snow simply disappear. Salt that’s dumped on top of ice relies on the sun or the friction of car tires driving over it to initially melt the ice to a slush that can mix with the salt and then won’t refreeze. For example, calcium chloride lowers the freezing point more than sodium chloride. Salt actually lowers the freezing temperature of the water. Why do we use road salt? More than 20 million tons of salt are used every year to melt snow and ice in cold northern regions. The actual reason that the application of salt causes ice to melt is that a solution of water and dissolved salt has a lower freezing point than pure water.

Salt that’s dumped on top of ice relies on the sun or the friction of car tires driving over it to initially melt the ice to a slush that can mix with the salt and then won’t refreeze. This phenomenon is called freezing point depression. Salt makes ice colder because the salt prevents melted water from freezing. Salt actually lowers the freezing temperature of the water.
