The magnesium ribbon is cleaned by rubbing with sandpaper before burning in the air. This is done to remove the protective layer of basic magnesium carbonate (Mg(CO3)2) from the ribbon’s surface. On the outside of the metal, the oxide layer forms a white coating that will not slowed down or interfere with the burning process. Sand paper rinsing helps to remove this oxide layer due to the fact that fire speeds are increasing. Unwanted impurities that have been tied to the ribbon can be removed, but reaction can only be used with pure magnesium. Magnesium reacts with oxygen to produce magnesium oxide, which does not burn.
Why Do We Rub Magnesium Ribbon With Sandpaper – Answer & Related Questions
Magnesium is a reactive metal that can react with the oxygen of air to produce a layer of MgO that can be slowing down or hindering the burning process. The magnesium ribbon should therefore be sandpaper-paper before igniting to remove this layer of oxide.
