Magnesium hydroxide is used as a laxative to relieve occasional constipation. Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide).It has an empirical formula of Mg O and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding. pH above a pH of 7.0, rendering this chemical safe to use from a Aries Chemical supplies liquid and dry magnesium hydroxide Mg (OH)2 for pH control, alkalinity addition and heavy metal precipitation.
