How Does Salt Melt Icy Roads. Instead it makes water less likely to freeze in a phenomenon called freezing point depression. Ice forms when the­ temperature of water reaches 32 degrees fahrenheit (0 degrees celsius), and that includes ice on roadways. 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 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. When liquid water freezes into ice, the loose water molecules arrange themselves into a more ordered. When the ionic compound salt is added to the equation, it lowers the freezing point of the water, which means the ice on the ground can’t freeze that layer of water at 32 °f anymore. Salt doesn’t directly melt ice, nor does it make snow simply disappear.
