Chemistry turns myth into reality.In this experiment we show how can we make a dragon's egg from two simple mixtures.
Reagents and equipment
- Iron(III) oxide
- Aluminium powder
- Potassium permanganate
- magnesium strip
- Sand
- Filter paper
- lighter
- Two beakers
- Plastic spoon
Procedure
- Fro preparing the mixture for the egg mix 20 gm of the iron(III) oxide and 25 gm of aluminium powder well.
- Then prepare the incendiary mixture by mixing 5 gm of aluminium powder and 5 gm of potassium permanganate.
- Take a cup of sand to localize the flame.
- Take a filter paper and cut a cone from it, place it in the center of sand
- Carefully pour the mixture for the egg and incendiary mixture into the cone.
- Use a magnesium strip as a wick. Light the wick!
Process
The mixture immediately ignites and emit sparks. When the reaction ends, the mixture turns into an incandescent egg at 2000oC.
A powdery mixture of aluminium iron(III) oxide is called thermite. It is ignited by a special incendiary mixture of potassium permanganate and aluminium powder. When it ignites, thermite burns intensely, releasing a huge amount of heat.
The mixture heat up to 2000oC. During the chemical reaction, aluminium reduces iron(III) oxide to metallic iron, and it self oxidizes to aluminium oxide. At a high temperature aluminium oxide bakes together with sand, forming a glass like shell. It is a method used to obtain pure metals.
