- Description
-
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). Elemental fluorine is produced from it. It is commonly used to etch glass and silicon wafers.
Hydrofluoric acid is mainly produced by treatment of the mineral Fluorite, CaF2, with concentrated sulfuric acid at approximately 265°C.
CaF2 + H2SO4 → 2 HF + CaSO4
Because of its high reactivity toward glass, hydrofluoric acid is stored in fluorinated plastic (often PTFE) containers.A 48% solution has a density of 1.15 g/mL.
