Diphosphorus pentoxide, also known as phosphorus pentoxide or phosphoric anhydride, is a chemical compound with the formula P2O5. It is a white or colorless, deliquescent, crystalline solid that is highly soluble in water, producing phosphoric acid.

Properties:

* Diphosphorus pentoxide is a strong desiccant and is used to remove water from gases and liquids.

* It is also used as a catalyst in the production of various chemicals, including sulfuric acid, nitric acid, and fertilizers.

* Diphosphorus pentoxide is a major source of phosphorus for plants and is used in the production of fertilizers.

* It is also used in the manufacture of glass, ceramics, and detergents.

Production:

Diphosphorus pentoxide is produced by the thermal decomposition of phosphoric acid:

4H3PO4 → P2O5 + 6H2O

The reaction is carried out at a temperature of around 200 °C.

Uses:
