Reactions of Fluorine |
Reactions with water |
Fluorine will react with water to produce oxygen and ozone.
|
2F2(g) + 2H2O(l)O2(g) + 4HF(aq) |
3F2(g) + 3H2O(l)O3(g) + 6HF(aq) |
Reactions with air |
Fluorine is not reactive towards oxygen or nitrogen. If will react with moisture in the air to produce oxygen, see above.
|
Reactions with halogens |
Fluorine reacts with chlorine at 225°C to form the interhalogen species ClF. The trifluoride chlorine(III) fluoride is also formed and the reaction does
not go to completion.
|
Cl2(g) + F2(g)2ClF(g) |
Cl2(g) + 3F2(g)2ClF3(g) |
Under more forcing conditions, excess fluorine reacts with chlorine at 350°C and 225 atmospheres pressure to form the interhalogen species ClF5.
|
Cl2(g) + 5F2(g)2ClF5(g) |
Fluorine reacts with bromine in the gas phase to form the interhalogen species BrF. The product is difficult to obtain pure since BrF disproportionates
at toom temperature to form bromine, Br2, and BrF3 and BrF5.
|
Br2(g) + F2(g)2BrF(g) |
3Br(g) + Br2(l)BrF3(l) |
5Br(g) + 2Br2(l)BrF5(l) |
Under more forcing conditions, excess fluorine reacts with bromine at 150°C to form the interhalogen species BrF5.
|
Br2(l) + 5F2(g)2BrF5(l) |
Fluorine reacts with iodine at about -45°C in CCl3F solvent to form the interhalogen species IF. The product is dificult to obtain pure since IF disproportionates at toom temperature
to form iodine, I2, and IF5.
|
I2(g) + F2(g)2IF(g) |
5IF(g) + 2I2(s)IF5(l) |
Reactions with acids |
With dilute acids, fluorine's reaction is probaly dominated by that with water, which produces oxygen and ozone.
|
2F2(g) + 2H2O(l)O2(g) + 4HF(aq) |
3F2(g) + 3H2O(l)O3(g) + 6HF(aq) |
Reactions with bases |
Fluorine reacts with dilute aqueous hydroxide solutions to form oxygen(II) fluoride. |
2F2(g) + 2OH-(aq)OF2(g) + 2F-(aq) + H2O(l) |
