Hydrogen fluoride
Hydrogen Fluoride
Hydrogen fluoride (pronunciation: /ˈhaɪdrədʒən ˈflʊəraɪd/) is a chemical compound with the formula HF. This colorless gas or liquid is the principal industrial source of fluorine, often in the aqueous form as hydrofluoric acid, and thus is the precursor to many important compounds including pharmaceuticals and polymers (e.g. Teflon).
Etymology
The term "Hydrogen fluoride" is derived from the elements that make up the compound: hydrogen and fluorine. Hydrogen is derived from the Greek 'hydro' and 'genes' meaning 'water' and 'creator' respectively. Fluorine is derived from the Latin 'fluere', meaning 'to flow'.
Chemical Properties
Hydrogen fluoride boils near room temperature, much higher than other hydrogen halides. It is a weak acid when dissolved in water. However, upon contact with moisture, including tissue, hydrogen fluoride immediately converts to hydrofluoric acid, which is highly corrosive and toxic, and requires immediate medical attention upon exposure.
