♤ When Magnesium ribbon is exposed in the atmosphere it form a layer of magnesium oxide on its surface.
♤ This layer of magnesium oxide is stable compound to prevent further reaction of magnesium with oxygen.
♤ Hence, it should be cleaned before burning in air to remove this layer so that the metal can be exposed to air properly.
