Hexafluorophosphoric acid

Hexafluorophosphoric acid

hydrogen hexafluorophosphate; hexafluoro phosphoric acid

CAS 16940-81-1

Chemical Formula HPF6

Molecular Weight 145.97 g/mol

Hexafluorophosphoric acid is a strong inorganic acid, often represented as HPF6, but typically found as a hydrate in solutions. It is a colorless, fuming liquid that contains the hexafluorophosphate anion (PF−6). This acid is used as a catalyst, in metal cleaning, and for forming protective coatings on metal surfaces. It's also known for its corrosive properties and can react with metals to release hydrogen gas.
