Magnesium hydroxide formation of expansive brucite. This reaction, one of the two main alkali-aggregate reaction (AAR) is also known as alkali-carbonate reaction. Magnesium hydroxide Magnesium hydroxide is the inorganic compound with the chemical formula Mg(OH). It occurs in nature as the mineral brucite. It is a white solid with low solubility in water (). Magnesium hydroxide is a common component of antacids, such as milk of magnesia, as well as laxatives. Combining a solution of many magnesium salts with alkaline water induces precipitation of solid Mg(OH): On a commercial scale, Mg(OH) is produced by treating seawater with lime (Ca(OH)). 600m of seawater
