8 (6.1), I, (C/D)
ANHYDROUS HYDROGEN FLOURIDE (fluorane) is an inorganic compound with chemical formula HF. It is a very poisonous, colorless gas or liquid that dissolves in water to yield an aqueous solution termed hydrofluoric acid. It is the principal industrial source of fluorine, often in the form of hydrofluoric acid, and is an important feedstock in the preparation of many important compounds including pharmaceuticals and polymers, e.g. polytetrafluoroethylene (PTFE).
What hydrogen fluoride is
Hydrogen fluoride is a chemical compound that contains fluorine. It can exist as a colorless gas or as a fuming liquid, or it can be dissolved in water.
When hydrogen fluoride is dissolved in water, it may be called hydrofluoric acid.
Hydrogen fluoride can be released when other fluoride-containing compounds such as ammonium fluoride are combined with water.
Where hydrogen fluoride is found and how it is used:
Hydrogen fluoride is used to make refrigerants, herbicides, pharmaceuticals, high-octane gasoline, aluminum, plastics, electrical components, and fluorescent light bulbs. Sixty percent of the hydrogen fluoride used in manufacturing is for processes to make refrigerants.
Hydrogen fluoride is also used for etching glass and metal.
