What Is Road Salt? Chemical Composition - ThoughtCo

Jul 09, 2019  How Road Salt Works . Road salt works by lowering the freezing point of water via a process termed freezing point depression.In a nutshell, the salt breaks into its component ions in a small amount of liquid water.The added particles make it more difficult for the water to freeze into ice, lowering the freezing point of the water. So, for road salt to work, there needs to be a tiny bit of ...
