How Does Calcium Chloride Melt Snow and Ice?

Knowing the science behind how snow and ice can get dissolve by calcium chloride can help clarify why it is a prevalent item when used for deicing. (CaCl2) is one of nature’s remarkable marvels. It’s a claim to fame salt with extraordinary properties that improve driving and walker wellbeing. Calcium chloride additionally eliminates unfortunate residue from the air we inhale and improves the exhibition of items that add to the supply of energy, food, and different basics of life.

Calcium chloride is refined from regular saline solutions found in sandstone developments underneath the earth. By processing normally happening saline solution, responses with brutal synthetic compounds used in other CaCl2 producing cycles can be evaded. The National Organic Standards Board characterizes the brackish water measure OxyChem uses to deliver CaCl2 as “non-engineered.”


While comparative artificially to shake salt, calcium chloride contributes three interesting and exceptionally important execution properties inaccessible from rock salt:

  1. It is hygroscopic, firmly pulling in dampness from its environmental factors.
  2. Strong calcium chloride is deliquescent, which means it can ingest enough dampness to change over to a fluid saline solution.
  3. At the point when broken up in the water, strong calcium chloride discharges heat in an exothermic response.

These three extraordinary properties of calcium chloride are exceptionally gainful to rapidly soften ice on walkways and steps. Softening velocity is dictated by how effectively a substance breaks down when presented to snow/ice to shape a brackish water arrangement. This saline solution brings down the point of solidification of water to dissolve extra snow and ice on contact. By attracting moisture from its environmental factors, CaCl2 makes saltwater quicker than different materials.

Clients will see added execution because the response that makes CaCl2 brackish water really delivers heat. This makes calcium chloride a more powerful deicer than rock salt and different materials that draw heat from a cool climate to start the dissolving cycle.


How clear are the upsides of calcium chloride’s substance properties? No compelling reason to trust us. Providers of rock salt mixes guarantee that even the limited quantity of CaCl2 they add to their items has a huge presentation effect. As complimenting as those cases seem to be, a small amount of calcium chloride won’t fundamentally change the presentation of rock salt. It takes pure calcium chloride to dissolve ice quicker and more thoroughly.
