HNO3 is a strong oxidising agent and as well as F2 . What will be the reaction when pure F2 gas is bubbled through 100% pure HNO3. I Google it but all suggests different reaction.

  • $\begingroup$ Many products are suggested including HF , O2 , H2O , NO ,, NO2 , NF3 , NO2FO etc... $\endgroup$ – Harsh jain Dec 3 '18 at 16:10

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