Chemical reactions

Reaction of fluorine with hydrogen

Fluorine reacts quickly with hydrogen, forming hydrogen fluoride. The reaction can be explosive under the right conditions [3]:

H2(g) + F2(g) 2 HF(g)

Reaction of fluorine with metals/metal ions

Sodium reacts with fluorine forming sodium fluoride [3]:

2 Na(s) + F2(g) 2 NaF(s)

The reaction with metals is a general reaction for most metals [3].

Selenium reacts with excess fluorine forming selenium(VI)fluoride [3]:

Se(s) + 3 F2(g) SeF6(s)

Tellurium reacts with excess fluorine forming tellurium(VI)fluoride [3]:

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 [3].

Kr(s) + F2(s) KrF2(s)

This compound decomposes when heating to room temperature.

Xenon can be brought to react with fluorine, F2 [3]:

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 [4].

Radon can be brought to react with fluorine, F2. The exact formula for the molecule is unknown, and usually written as RnFn [3].

Reaction of fluorine with phosphorous

Phosphorous reacts with excess F2 forming phosphorous(V)fluoride [3].

2 P(s) + 5 F2(g) 2 PF5(s)

with excess phosphorous [3], 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 [3]:

S(s) + 3 F2(g) SF6(s)

Fluorine reacts with SO2 forming SO2F2 [3]:

SO2(g) + F2(g) SO2F2(g)

Reaction of fluorine with water

Fluorine reacts with water [3]:

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 [3]:

F2(g) + H2O(s) HOF(g) + HF(g)
