hydrofluoric acid[¦hī·drə′flu̇r·ik ′as·əd] (inorganic chemistry) An aqueous solution of hydrogen fluoride, HF; colorless, fuming, poisonous liquid; extremely corrosive, it is a weak acid as compared to hydrochloric acid, but will attack glass and other silica materials; used to polish, frost, and etch glass, to pickle copper, brass, and alloy steels, to clean stone and brick, to acidize oil wells, and to dissolve ores. Hydrofluoric Acid an aqueous solution of hydrogen fluoride, HF. Hydrogen fluoride is soluble in water in any proportions. The azeotropic mixture contains 38.26 percent HF and has a boiling point of 112°C (750 mm Hg) and a density of 1.138 g/cm3. Hydrofluoric acid reacts with oxides to form fluorides. It dissolves fluorides, forming complex compounds with them; it reacts vigorously with silicate materials, especially glass. It is used as a solvent and as a reagent in the preparation of fluorides; it is also used for etching glass. REFERENCESSee references under .hydrofluoric acid
