Properties[change | change source]

Antimony pentafluoride is a colorless thick liquid. It is a powerful oxidizing agent and very reactive. It can help fluorine to oxidize oxygen. This is not normal as oxygen normally oxidizes other things; it does not get oxidized. It can make very strong acids when mixed with hydrofluoric acid. It was used in the first reaction that used fluorides to make fluorine.

Preparation[change | change source]

It is made by reacting antimony pentoxide or antimony pentachloride with hydrofluoric acid. It can also be made by reacting antimony trifluoride with fluorine.

Uses[change | change source]

It is used to make very strong acids.

Safety[change | change source]

Antimony pentafluoride reacts with most chemical compounds. It is extremely corrosive.
