Wikipedia

Hydrofluoric acid

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.

Examples of use of hydrofluoric acid
1. Police sealed off the Prva Iskra factory, which produces explosives as well as toxic hydrofluoric acid, used as a component for household detergents.
