It has an empirical formula of Mg O and consists of a lattice of Mg 2+ ions and O 2â ions held together by ionic bonding. Magnesium hydroxide forms in the presence of water (MgO + H 2 O â Mg(OH) 2), but it can be reversed by heating it to separate moisture.agnesium oxide is easily made by burning magnesium ribbon, which produces a very bright white light, and a powdery ash. The bright flame is very hard to extinguish and it emits a harmful intensity of UV light. Inhalation of magnesium oxide fumes can cause metal fume fever.
In Trial 1, the empirical formula of magnesium oxide = Mg2O3. In Trial 2, the empirical formula of magnesium oxide = MgO. A strip of magnesium metal reacts with oxygen in the air to produce magnesium oxide. In order to experimentally determine the percentage composition and empirical formula of magnesium oxide, a piece of magnesium is heated strongly to react with the oxygen in the air.
