Dinitrogen pentoxide
Dinitrogen pentoxide is a chemical compound. It is made by removing water from nitric acid, so it is also called nitric anhydride. Its chemical formula is N
2O
5. It is a powerful oxidizing agent. It is a white solid.
It is made by reacting phosphorus(V) oxide with nitric acid. The phosphorus(V) oxide removes the water from the nitric acid. It can be used as an alternative to nitric acid to add the nitro group –NO
2 to some chemical compounds.[1] It is toxic as it can make nitrogen dioxide gas.
