To remove the oxide layer that is formed by being in contact with air. Sand paper will scratch off this layer so that this oxide layer does not prevent the reaction.

Magnesium, being a reactive metal in the activity series, gets easily reacted when comes in contact with oxygen. Thus magnesium oxide is formed.In order to get appropriate results, it has to be cleaned, so that magnesium oxide is removed and the experiment is successfully performed.

When exposed to air many metals will slowly react with oxygen in the atmosphere to form metal oxides and Magnesium is one of those metals. You are probably familiar with rust which is simply the oxide that forms when iron is exposed to oxygen in the air. With magnesium, the oxide layer forms a white...

When exposed to air many metals will slowly react with oxygen in the atmosphere to form metal oxides and Magnesium is one of those metals. You are probably familiar with rust which is simply the oxide that forms when iron is exposed to oxygen in the air. With magnesium, the oxide layer forms a white coating on the outside of the metal that will slow down or interfere with the burning process. The ribbons should be sanded with a fine sandpaper, therefore, to remove the layer. Burning magnesium results in magnesium oxide and also some magnesium nitride (reaction with nitrogen in the air). Burning speeds up the conversion of magnesium to magnesium oxide in air. read less
