Magnesium Oxide Oxygen

Magnesiumoxide is also known as magnesia which is a mineral. It is white in color and solid in state. It is a foundation of magnesium. Its practicalformula is MgO. It is synthesized by an ionic bond which occurs betweenone magnesium and one oxygen atom. In nature, it is hygroscopic. When magnesium oxide reacts with water, it forms magnesium hydroxide. This reaction can be reversed by the process of heating.

MgO + H2O → Mg(OH)2

Reaction of magnesium with oxygen:

Whenmagnesium metal is burned in air, magnesium oxide is formed. This is anoxidation/reduction reaction because it shows the burning of a metal, as the products of this reaction are visible afterwards and it produces alot of light.


2 Mg(s ) + O2(g `->` 2 MgO(s )

3 Mg(s ) + N2(g ) `->` Mg3N2(s )


  1. Whenmagnesium oxide is treated with water and consumed, its properties allow it to liberate large amounts of oxygen. The additional oxygen which is present in the intestinal tract encourages healthy, aerobic bacteria. Meanwhile it inhibits the growth of unhealthy bacteria and fungi.
  2. In the industrial cables, magnesium oxide acts as insulator. It is a basic refractory material which can be used for crucibles. It also acts as a principal fireproofing ingredient used in construction materials.
  3. Magnesiumoxide varies from other laxatives. Also used to stimulate intestinal cleansing without the crabbing and limiting pain associated with other laxatives.
  4. Magnesium actsas a natural sedative for nervous system and is normally used in clinical practice to help nervousness, insomnia and high blood pressure.
  5. Magnesium oxide is used for aid of heartburn and sore stomach as an antacid and as a short-term laxative.


Magnesiumoxide is normally produced by magnesium ribbon in burning state. It oxidizes in a bright light of white color which results in a form of powder. As, the bright flame is difficult for extinguishing, it releasesa UV light which is of very harmful intensity.
