Physical Properties
White amorphous powder. Soluble in sulfuric acid, insoluble in acetone, ammonia.
Soluble in water, release a large amount of heat, first formed metaphosphate, pyrophosphate, eventually turned into orthophosphoric acid. Moist solution absorption in the air. Contact with the organic burning will happen. Contact with organic matter caused combustion was in danger. Heated or meet water heat liberation, let out poisonous corrosive flue gas. Has a strong corrosive.Phosphorus pentoxide is phosphoric acid anhydride.
