WebPhosphorus (V) oxide, P 4 O 10, is a white powder that is prepared by burning phosphorus in excess oxygen. Its enthalpy of formation is very high (−2984 kJ), and it is quite stable and a very poor oxidizing agent. Dropping P 4 O 10 into water produces a hissing sound, heat, and orthophosphoric acid: P 4 O 10 ( s) + 6H 2 O ( l) 4H 3 PO 4 ( a q) WebPhosphorus (V) oxide reacts violently with water to give a solution containing a mixture of acids, the nature of which depends on the conditions.
