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

Answer» Magnesium ribbon should be cleaned before burning it in air to remove the oxide layer from it which may prevent or slow down the burning of magnesium ribbon. Magnesium ribbon should be cleaned with sandpaper before burning in air because Magnesium is very reactive element which rapidly reacts with oxygen in the air to form a white layer of magnesium oxide, which may prevent or slow down the burning of magnesium ribbon . |
