Gas introduction
Hydrogen fluoride is an inorganic compound with a chemical formula of HF. Under normal conditions, it is a colorless, pungent, toxic gas with a strong hygroscopicity. It produces white smoke when it comes into contact with air. It is easily soluble in water and can be infinitely miscible with water to form hydrofluoric acid. Hydrogen fluoride molecules have hydrogen bonds and can exhibit some abnormal properties, such as a much higher boiling point than other hydrogen halides. Hydrogen fluoride is highly chemically reactive and can react with many compounds. Hydrogen fluoride as a solute is a weak acid, while pure hydrogen fluoride is a strong acid.
