_Arsenious anhydride_ also affords a brilliant combustion, forming the
liquid trifluoride of arsenic, AsF_{3}. This liquid in turn appears to
react with more fluorine with considerable evolution of heat, probably
forming the pentafluoride, AsF_{5}. _Chloride of arsenic_, AsCl_{3},
is converted with considerable energy to the trifluoride, free
chlorine being liberated.
_Carbon bisulphide_ inflames in the cold in contact with fluorine, and
if the fluorine is led into the midst of the liquid a similar
production of flame occurs under the surface of the liquid, as in case
of nitric acid. No carbon is deposited, both the carbon and sulphur
being entirely converted into gaseous fluorides.
_Carbon tetrachloride_, as previously mentioned, reacts only very
slowly with fluorine. The liquid may be saturated with gaseous
fluorine at 15 deg., but on boiling this liquid a gaseous mixture is
evolved, one constituent of which is carbon tetrafluoride, CF_{4}, a
gas readily capable of absorption by alcoholic potash.
