Bright burning and the formation of thick smoke
name: Oxidation of phosphorus in the presence of chlorine
Wear eye protection goggles. Use gloves. Chlorine is a poisonous gas! Perform the reaction in a hood or outdoors.
Always follow general safety
recommendations. Please note that conducting chemistry
experiments you must comply with the relevant legal procedures in
As a halogen chlorine is a strong oxidant. This property of chlorine is due to its position in the periodic table, high electronegativity, the lack of a single electron to fill the outer electron level and the low energy of Cl-Cl bonds. Phosphorus is a nonmetal that has reducing properties. It, especially white phosphorus, has a very high reactivity. Phosphorus is oxidized to phosphorus chloride, which forms the smoke. A large amount of heat is released which provides the ignition.
