Potassium burns in air. A piece of potassium (K) metal is melted in a deflagration spoon using a Bunsen burner. Molten hot potassium then starts burning. Potassium reacts with oxygen (O2) in the air to produce a mixture of potassium peroxide (K2O2) and potassium superoxide (KO2): K + O2 -> K2O2 and K + O2 -> KO2. In the process the metal and the oxidation products creep up along the walls and over the rim of the spoon. | |
