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

  • -1

Magnesium is a reactive metal. It should be burned directly in air without cleaning.  Still, it is cleaned before buruning. It is unnecessarily cleaned before burning.

      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.
