Fluorine nitrate is an unstable derivative of nitric acid with the formula FNO
3. It is shock-sensitive.[1] Due to its instability, it is often produced from chlorine nitrate as needed[citation needed].
Synthesis and properties
Fluorine nitrate is formed when fluorine gas is bubbled through nitric acid or reacted with solid potassium nitrate:[2]
- F2 + HNO3 → FNO3 + HF
- F2 + KNO3 → FNO3 + KF
It decomposes in water to form oxygen gas, oxygen difluoride, hydrofluoric acid, and nitric acid.[1]
