MAGNESIUM RIBBON WHICH IS EXPOSED TO ATMOSPHERE REACTS WITH OXYGEN GAS PRESENT IN THE ATMOSPHERE AND FORMS AN OXIDE COAT OVER THE MAGNESIUM RIBBON. THIS COATING ACTS AS A PROTECTIVE COATING WHICH PREVENT FURTHER OXIDATION OF THE MAGNESIUM RIBBON .IF THIS LAYER IS NOT REMOVED IT MAY AFFECT THE RESULT OF THE REACTION THAT HAS TO BE CARRIED OUT.
The magnesium ribbon should be cleaned before burning in the air because the layer of magnesium oxide (which is formed due to the reaction of magnesium with air ) can be removed in order to get the desired chemical reaction. Also in order to remove the oxide layer, the presence of which slowdowns the oxidation process
