"Sweet fire" experiment
How to make bicolour flame using sugar and potassium permanganate
Experiments with potassium permanganate are perhaps the most interesting and straightforward, but they are also quite dangerous. These experiments can involve a change of color, explosions or burning.
Reagents and equipment:
- potassium permanganate;
- matches or lighter.
Sugar does not burn in itself, but melts. But if it is mixed with potassium permanganate and lit, the mixture burns with a yellow-blue flame. The potassium permanganate, as a strong oxidizer, oxidizes the sugar and it burns.
C₁₂H₂₂O₁₁ + 16KMnO₄ = 16MnO₂ + 8K₂CO₃ + 11H₂O + 4CO₂
Wear protective gloves and glasses when conducting this experiment, and follow safety rules for working with fire.
