Uses:
Magnesium chloride is also used in several medical and topical (skin-related) applications. It has been used in pills as supplemental sources of magnesium, where it serves as a soluble compound which is not as laxative as MgSO4, and more bio-available than Mg(OH)2 and MgO, since it does not require stomach acid to produce soluble Mg2+ ion. It can also be used as an effective anesthetic for cephalopods, some species of crustaceans, and several species of bivalves, including oysters.
Magnesium chloride is an important coagulant used in the preparation of "tofu" from soy milk. In Japan, it is sold as "Nigari", (derived from the Japanese word for "bitter"). It is a white powder produced from seawater after the sodium chloride has been removed, and the water evaporated. In China, it is called "Lushui",Nigari or Lushui and consists mostly of magnesium chloride, with some MgSO4 and other trace elements. It is also an ingredient in baby formula milk.
Magnesium chloride has shown promise as a storage material for hydrogen gas. Ammonia can be effectively adsorbed onto solid magnesium chloride, forming Mg(NH3)6Cl2. When the ammonia is released by mild heat, and is then passed through a catalyst, hydrogen gas is retrieved.
Description:
Magnesium chloride,MgCI2,also known as chloromagnesite, is a colorless crystalline solid. It is soluble in water and alcohol and is used in the ceramic and textile industries. Magnesium chloride is formed by heating hydrated magnesium chloride crystals in a current of dry hydrogen chloride or by heating magnesium ammonium chloride. Hydrated magnesium chloride, MgCI2·6H20 , also known as bischophite,is a white deliquescent solid formed by the reaction of magnesium carbonate(or hydroxide,oxide or metal)and hydrogen chloride. It is used in disinfectants, fire extinguishers, and paper manufacture.
