Description

Hexafluorosilicic acid is an inorganic compound with the chemical formula (H 3O) 2SiF 6 (also written as (H 3O) 2[SiF 6]). It is a colorless liquid rarely encountered undiluted. Hexafluorosilicic acid has a distinctive sour taste and pungent smell. It is mainly produced as a precursor to aluminum trifluoride and synthetic cryolite. It is commonly used as a source of fluoride for water fluoridation. Concentrated hexafluorosilicic acid is corrosive and toxic, but in everyday use, it is so diluted as to be less harmful.
In aqueous solution, the hydronium cation (H3O+) is traditionally equated with a solvated proton, and as such, the formula for this compound is often written as H 2SiF 6. Extending that metaphor, the isolated compound is then written as H 2SiF 6·2H 2O.
