# What is the reaction between nitric acid and fluorine?

Nitric acid, $$\ce{HNO3}$$, is a strong oxidising agent as well as fluorine, $$\ce{F2}$$. What will be the reaction when pure $$\ce{F2}$$ gas is bubbled through 100% pure $$\ce{HNO3}$$. While searching, many products are suggested including $$\ce{HF}$$, $$\ce{O2}$$, $$\ce{H2O}$$, $$\ce{NO}$$, $$\ce{NO2}$$, $$\ce{NF3}$$, $$\ce{NO2FO}$$, etc.. What is correct?

It was first discovered by Cady that when fluorine is bubbled through $$\pu{3 N}$$ nitric acid, then a remarkable compound, fluorine nitrate ($$\ce{FNO3}$$) is formed. It boils at $$\pu{-42 ^\circ C}$$ and is a very strong oxidizing agent and is capable of liberating iodine from iodides and in gaseous states, it explodes around $$\pu{200-300 ^\circ C}$$.
