Applications
Phosphorus(V) oxide is used as a drying and dehydrating agent, a condensation reagent in organic synthesis and a laboratory reagent. It is also used in sugar refining and in fire extinguishing. Phosphorus pentoxide in DMSO forms an Onodera reagent which oxidizes alcohols. It is capable of converting mineral acids to anhydrides.

Solubility
Soluble in sulfuric acid. Insoluble in acetone and ammonia. Decomposes in water.

Notes
It is highly hygroscopic in nature and gets hydrolyzed to phosphoric acid. It is stored in a separate safety cabinet away from incompatibles such as alkalis and water.
