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 )
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.
