Is magnesium chloride bad for concrete?
MAG was once thought to be a safe and powerful ice melting solution. However, today there is much scientific information and evidence on the concrete damaging effects of magnesium chloride. While deicing salts containing sodium, potassium and calcium are chemically innocuous to concrete, this is not true of magnesium.
Magnesium Salts (technically called Magnesium Chloride), is the compound you find in all Magnesium supplements and it has a different molecular structure than Epsom Salts. The molecular structure of Magnesium Chloride is much more easily absorbed into the body than that of Epsom Salt.
- This medication is a mineral supplement used to prevent and treat low amounts of magnesium in the blood. Magnesium is very important for the normal functioning of cells, nerves, muscles, bones, and the heart. Usually, a well-balanced diet provides normal blood levels of magnesium.
- It feels slippery like oil, but it is a solution of magnesium chloride flakes in water. (I recommend Ancient Minerals magnesium flakes.) You can purchase magnesium oil, but making it yourself provides a WAY more economical option. It provides the benefits of magnesium supplementation in an absorbable form.
- Magnesium citrate is a magnesium preparation in salt form with citric acid in a 1:1 ratio (1 magnesium atom per citrate molecule). Magnesium citrate is used medicinally as a saline laxative and to completely empty the bowel prior to a major surgery or colonoscopy.
MgCl2 is a generally considered to be a neutral salt. This compound can be formed from the reaction of Mg(OH)2 (a strong base) and HCl (a strong acid). Salt formed by combining strong acid and weak base are acidic in nature. MgCl2 is prepared by weak base Mg(OH)2 and HCl, Thus it is slightly acidic in nature.
- Salts: AgNO3(Salt), NaCl(Salt), NaNO3(salt), KNO3(salt), Acids: H3PO4(acid), HCl(acid), H2SO4(acid), HC2H3O2(acid), HNO3(acid), H2SO3(acid) Bases: Mg(OH)2(base), NaOH(base), KOHbase), NH4OH(base).
- Being highly water soluble, magnesium nitrate occurs naturally only in mines and caverns as nitromagnesite (hexahydrate form). The magnesium nitrate used in commerce is made by the reaction of nitric acid and various magnesium salts.
- A strong acid is one that completely ionizes or dissociates in a solution ,provided there is sufficient solvent. In contrast, a weak acid only partially dissociates. Acids like acetic acid ( CH3COOH ) dissociates partially or incompletely, releasing only some of its hydrogen atoms into the solution.
Magnesium chloride deicer may offer net environmental benefits if its use leads to a reduction in the quantity of salt and sand applied to roadways. The environmental safety of magnesium chloride deicer depends, however, on low concentrations of contaminants and avoidance of rust inhibitors containing phosphorus.
- Similar to calcium chloride, magnesium chloride melts ice at a quick pace. This is because it is hygroscopic which simply means it that it absorbs moisture. This helps the ice melter to dissolve into a brine faster which instigates the melting of the ice surrounding it.
- The most common, and often sole ingredient in ice melters labeled “Pet Safe,” is Urea (sometimes listed as Carbonyl Diamide or Carbamide Resin). Urea is a bio-degradable chemical that is most commonly used in fertilizers. Although Urea won't harm your pet's paws, it also won't melt your ice. Your pet will thank you.
- Calcium chloride (CaCl2) is a deliquescent salt, which means that it turns to water by absorbing moisture in the air. Its ability to absorb moisture makes it useful in several commercial applications. Nordic Power Desiccant uses calcium chloride as an absorbent. It is therefore non-toxic and environmentally friendly.
