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)
