Magnesium oxide synthesis

3synthesis methods
Magnesium oxide is easily formed by burning magnesium metal ribbon. Mg oxidizes and emits a bright white light, rich in ultraviolet and hard to extinguish. Extreme care must be taken if MgO is to be prepared by this method. Magnesia is a white solid mineral that occurs naturally as “Periclase” and is used as a source of magnesium metal. Magnesium oxide is hygroscopic in nature and care must be taken to protect it from moisture. It reacts with water and forms the hydroxide:
MgO＋H2O→Mg(OH)2
However, this reaction can be reversed by heating it to remove moisture.

Reaction Conditions:

in gas;Mg was resistively heated to 700°C, and the metal vapor was entrained in an Ar carrier gas and allowed to react with N2O;;
