sorry not sorry


Preparing a nitrating solution from 100% nitric acid and phosphorous pentoxide. 

Just a few short notes: the 98-100% nitric acid (first pics) is a quite strong oxidizer. If I would spill it on my gloves it would ignite it in no time. Same would happen if I would spill it on my labcoat. 

On the second pics the prepared nitrating mixture is seen. It is a bit like honey, especially when it’s cold. The only difference that it releases toxic fumes (as seen) and if I would like to taste it it would cause very-very serious burns

From the reaction of pure nitric acid and phosphorous pentoxide, nitrogen pentoxide is generated what is also known as the anhydrous form of nitric acid: N2O5 + H2O = 2 HNO3.

The dinitrogen pentoxide is a highly reactive white powder, melting at 41 °C. When it contacts with water, even with the humidity of the air, it produces nitric acid what is quite corrosive. However, it is a great reagent if you would like to prepare a nitrate ester of any compound what you found on the schelf.
