हवा में जलने से पहले मैग्नीशियम रिबन को साफ किया जाना चाहिए ताकि वांछित रासायनिक प्रतिक्रिया प्राप्त करने के लिए मैग्नीशियम ऑक्साइड (जिसे हवा के साथ मैग्नीशियम की प्रतिक्रिया के कारण बनाया गया हो) की परत हट सके।

♤ 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.
