Formation of Phosphorus Pentoxide

P4 + 5O2 → P4O10

Visão geral

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.
