These experiments can involve a change of color, explosions or burning. Reagents and equipment: * potassium permanganate; * sugar; * beaker; * matches or lighter. Step-by-step instructions Mix potassium permanganate and sugar in a beaker in a ratio of 1:1. Light the mixture. The mixture burns. Processes description 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
