Why & How Does Salt Melt Ice?

Why Does Salt Melt Ice

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. Continue reading

Study Shows Environmental Road Salting Proves Effective

For Immediate Release: April 14, 2017, by the Salt Institute

Naples, FL- A new study published in the Proceedings of the Natural Academy of the Sciences (Salting our freshwater lakes) purports to sound the alarm about rising chloride levels in North American lakes. The study actually found that chloride levels in the majority of the examined lakes either stayed the same or declined and that chloride levels were far below EPA toxicity standards. Chloride concentrations across all 371 lakes in the study had a median of 6 milligrams per liter, while the EPA standard is 230 mg/L.  Continue reading
