Hydrofluoric acid is a colorless, transparent liquid, strongly acidic, and highly corrosive to metals and glass.

Hydrofluoric acid plays an important role in the purification of aluminum and uranium due to its ability to dissolve oxides. Hydrofluoric acid is also used to etch glass, engraving patterns, marking scales and text; the semiconductor industry uses it to remove oxides from silicon surfaces, which can be used in alkylation of isobutane and n-butene in refineries. The catalyst also uses hydrofluoric acid in the "soaking" process of removing oxygen-containing impurities from the surface of the stainless steel. Formula: HF

Since the ability to bond between a hydrogen atom and a fluorine atom is relatively strong, and hydrogen bonds exist between hydrogen fluoride molecules in an aqueous solution, hydrofluoric acid cannot be completely ionized in water, so theoretically a low concentration of hydrofluoric acid is a weak acid. It is extremely corrosive and can strongly corrode metals, glass and silicon-containing objects. Inhalation of vapors or contact with the skin can cause intractable burns. The laboratory is usually made of fluorite (mainly calcium fluoride) and concentrated sulfuric acid. It needs to be sealed in a plastic bottle and kept in a cool place.
