Salt is the primary ingredient in most ice melt products because it lowers the freezing point of water.  This is referred to as “freezing point depression.”  In its pure state, water freezes at 32°F.  Even though it may not be visible, molecular water is always present on the surface of ice. When salt comes in contact with water, it starts to dissolve creating a solution referred to as brine which subsequently lowers the freezing point and melts the ice around it.…
