Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water. Solutions of HF are colourless, acidic and highly corrosive. It is used to make most fluorine-containing compounds; examples include the commonly used pharmaceutical antidepressant medication fluoxetine (Prozac) and the material PTFE (Teflon). … See more Production of organofluorine compounds The principal use of hydrofluoric acid is in organofluorine chemistry. Many organofluorine compounds are prepared using HF as the fluorine source, including Teflon See more In dilute aqueous solution hydrogen fluoride behaves as a weak acid, Infrared spectroscopy has been used to show that, in solution, dissociation is accompanied by formation of the See more In addition to being a highly corrosive liquid, hydrofluoric acid is also a powerful contact poison. Because of the ability of hydrofluoric acid to penetrate tissue, poisoning can occur readily through exposure of skin or eyes, or when inhaled or swallowed. … See more • International Chemical Safety Card 0283 • NIOSH Pocket Guide to Chemical Hazards • CID 14917 from PubChem (HF) See more Hydrofluoric acid was first prepared in 1771, by Carl Wilhelm Scheele.
