- Clean a magnesium ribbon about 3-4 cm long by rubbing it with sandpaper.
- Hold it with a pair of tongs.
- Burn it using a spirit lamp or burner and collect the ash so formed in a watch glass as shown in fig.1.1. Burn the magnesium ribbon keeping it away as far as possible from your eyes.
We have observed that magnesium ribbon burns with a dazzling white flame changes into a white powder. The powder is magnesium oxide. It is formed due to the reaction between magnesium and oxygen present in the air.
