Magnesium is a silvery – white strong lightweight metal. Although commercially viable concentrations are available in minerals, most magnesium is obtained from electrolysis of brines, wells, or seawater.
magnesium oxide is used in some antacids, in making crucibles and insulating materials, in refining some metals from their ores and in some types of cements. When combined with water (h2o), magnesia forms magnesium hydroxide (mg(oh)2), better known as milk of magnesia, which is commonly used as an antacid and as a laxative.
