General conclusions

Magnesium hydroxide, Mg(OH)2, otherwise known as milk of magnesia, is commonly used as an antacid or a laxative. The mineral form of magnesium hydroxide is known as brucite. Magnesium hydroxide interferes with the absorption of folic acid and iron. Magnesium hydroxide is used on a short-term basis to treat constipation. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. It can be prepared by three general ways:

Mg3N2(s) + H2O(l) --> 2NH3(g) + Mg(OH)2(aq)
Solid Magnesium nitride + Water = Ammonia + Aqueous Magnesium Hydroxide

MgO(s) + H2O(l) --> Mg(OH)2(aq)
Solid Magnesium oxide + Water = Aqueous Magnesium Hydroxide

Mg(s) + 2H2O --> Mg(OH)2(aq) + H2(g)
Solid Magnesium + Water = Aqueous Magnesium Hydroxide + Hydrogen Gas
