How P2O5 compound is formed??
  • 1 answers

Gurjeet Singh 7 years, 8 months ago

Phosphorus pentoxide is a chemical compound with the molecular formula - P4O10. Its common name is derived from its empirical formula - P2O5

P4O10 is prepared by burning elemental phosphorus in sufficient supply of air:

P4 + 5O2 P4O10

Phosphorus pentoxide is not flammable but it reacts vigorously with water and water-containing substances like wood or cotton, liberates much heat and may even cause fire.
