Question

Why should a magnesium ribbon be cleaned before burning in air?​

Answer 1

When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. ... After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction.Magnesium ribbon must be cleaned before burning in air so that the layer of magnesium oxide (which is formed due to reaction of magnesium with air) can be removed in order to get the desired chemical reaction.
