Solutions of hf are colorless, acidic and highly corrosive Hydrogen fluoride, hydrogen chloride, hydrogen bromide and hydrogen iodide 70%) and pure hf has a boiling point near room temperature.

When hydrogen fluoride is dissolved in water, it may be called hydrofluoric acid
Hydrogen fluoride can be made when other compounds with fluoride, such as ammonium fluoride, are mixed with water.
Fluoride interacts with many cations, including hydrogen and a wide variety of metals It is the only halide with a positive pk a (3.2), and therefore exists in acidic environments as its protonated form (hf) Hf, commonly released as industrial or volcanic fumes, turns gaseous above 20. Hydrogen fluoride is a key component in the making of fluorocarbons, which are used in aerosols and refrigerants.
Dental fluoride helps prevent tooth decay by making your enamel more resistant to acid attacks It also reverses early decay Many foods and water contain fluoride You can also purchase fluoride toothpaste and mouthwash
Hydrofluoric acid (hf) is a clear, colorless, inorganic acid that is used in research and industry for its ability to etch glass, metal and silicon compounds
It is also an essential tool for semiconductor and electronic fabrication and mineral processing. Fluoridation chemicals are the major source of ingested fluoride in the u.s., contributing over 50% of total daily intake at all ages due to the widespread practice of water fluoridation. This page discusses the acidity of the hydrogen halides
