Magnesium chloride salts is rare in healthy individuals with a normal diet, because excess magnesium is readily excreted in urine by the kidneys. A few cases of oral magnesium toxicity have been described in persons with normal renal function ingesting large amounts of magnesium salts, but it is rare. If a large amount of magnesium chloride is eaten, it will have effects similar to magnesium sulfate, causing diarrhea, although the sulfate also contributes to the laxative effect in magnesium sulfate, so the effect from the chloride is not as severe. Chloride (Cl) and magnesium (Mg) are both essential nutrients important for normal
Magnesium carbonate Magnesium carbonate Magnesium carbonate, MgCO (archaic name magnesia alba), is an inorganic salt that is a white solid. Several hydrated and basic forms of magnesium carbonate also exist as minerals. The most common magnesium carbonate forms are the anhydrous salt called "magnesite" (MgCO) and the di, tri, and pentahydrates known as "barringtonite" (MgCO·2 HO), "nesquehonite" (MgCO·3 HO), and "lansfordite" (MgCO·5 HO), respectively. Some basic forms such as "artinite" (MgCO·Mg(OH)·3 HO), "hydromagnesite" (4 MgCO·Mg(OH)·4 HO), and "dypingite" (4 MgCO· Mg(OH)·5 HO) also occur as minerals. Magnesite consists of white trigonal crystals. The anhydrous salt is practically insoluble in water, acetone, and
