Formation of Phosphorus Pentoxide

P₄ + 5O₂ → P₄O₁₀

Tổng quan

White phosphorus burns vigorously in oxygen to form phosphorus pentoxide, an extremely powerful desiccant. The reaction is highly exothermic and phosphorus can spontaneously ignite in air. Phosphorus pentoxide reacts violently with water to form phosphoric acid.
