Application

Hydrofluoric Acid is a clear, colorless, smoky, corrosive liquid in aqueous solution of hydrogen fluoride gas, with a sharp,
pungent odor. Hydrofluoric acid is a weak acid that is extremely corrosive and can strongly corrode metals, glass and objects
containing silicon. Burns that are difficult to heal if they are inhaled or come into contact with skin. Fluorite (calcium
fluoride) and concentrated sulphuric acid are commonly used in laboratories, sealed in plastic bottles and kept in a cool place.
