Reaction of fluorine with hydrogen
Fluorine reacts quickly with hydrogen, forming hydrogen fluoride. The reaction can be explosive under the right conditions :
H2(g) + F2(g) 2 HF(g)
Reaction of fluorine with metals/metal ions
Sodium reacts with fluorine forming sodium fluoride :
2 Na(s) + F2(g) 2 NaF(s)
The reaction with metals is a general reaction for most metals .
Selenium reacts with excess fluorine forming selenium(VI)fluoride :
Se(s) + 3 F2(g) SeF6(s)
Tellurium reacts with excess fluorine forming tellurium(VI)fluoride :
Te(s) + 3 F2(g) TeF6(s)
Reaction of fluorine with noble gasses
Krypton will react with fluorine, F2, when cooled to -196 °C (liquid nitrogen) and zapped with an electric discharge or X-rays, forming krypton(II) fluoride, KrF2 .
Kr(s) + F2(s) KrF2(s)
This compound decomposes when heating to room temperature.
Xenon can be brought to react with fluorine, F2 :
Xe(g) + 2 F2(g) XeF4(s), mix gasses at 400 °C then cool to -78 °C
Xe(g) + F2(g) XeF2(s)
Xe(g) + 3 F2(g) XeF6(s)
The xenon fluorides are used for synthesis of other xenon compounds .
Radon can be brought to react with fluorine, F2. The exact formula for the molecule is unknown, and usually written as RnFn .
Reaction of fluorine with phosphorous
Phosphorous reacts with excess F2 forming phosphorous(V)fluoride .
2 P(s) + 5 F2(g) 2 PF5(s)
with excess phosphorous , the reaction is
2 P(s) + 3 F2(g) 2 PF3(s)
PF3(s) + F2(g) PF5(s)
Reaction of fluorine with sulfur
Sulfur reacts with excess fluorine forming sulfur(VI)fluoride :
S(s) + 3 F2(g) SF6(s)
Fluorine reacts with SO2 forming SO2F2 :
SO2(g) + F2(g) SO2F2(g)
Reaction of fluorine with water
Fluorine reacts with water :
F2(g) + H2O(l) O2(g) + OF2(aq) + H2O2(aq) + HF(aq)
The balancing of the reaction, i.e. the distribution of products depends on the reaction conditions.
If the water is frozen, fluorine reacts with ice :
F2(g) + H2O(s) HOF(g) + HF(g)
