The trifluoride, in turn, combines with more fluorine to form the pentafluoride, the reaction being accompanied by the appearance of a flame of comparatively low temperature.

_Pentachloride and trichloride of phosphorus_ both react most energetically with fluorine, instantly producing a brilliant flame, and evolving a mixture of phosphorus pentafluoride and free chlorine.

If the current of fluorine is fairly rapid, a colorless fuming liquid condenses in the receiver, which is mainly arsenic trifluoride, AsF_ {3}, but which appears also to contain a new fluoride, the pentafluoride, AsF_ {5}, inasmuch as the solution in water yields the reactions of both arsenious and arsenic acids.

This liquid in turn appears to react with more fluorine with considerable evolution of heat, probably forming the pentafluoride, AsF_ {5}.

If, on the contrary, the phosphorus is in excess, a gaseous mixture of this pentafluoride with a new fluoride, the trifluoride, PF_ {3}, a gas insoluble in water, but which may be absorbed by caustic potash, is obtained.

The phosphorous pentafluoride rains out when the weather gets cold.
