Hydrofluoric acid

CAS number :

Molecular weight :7664-39-3

Molecular formula/chemical symbol :HF

Description :

Hydrofluoric acid (HF) is a solution of hydrogen fluoride in water.[2] Its chemical formula is HF. It is a weak acid, but very corrosive and extremely toxic. It can dissolve glass to make hexafluorosilicic acid. If it gets on the skin, it can kill you. It is made by reacting fluorite with sulfuric acid. It is used in the processing of petroleum. It is also used to make various other chemicals containing fluorine, such as teflon (the coating in a frying pan), freon (the cooling agent in an air conditioner), and fluorocarbons (used as propellants in aerosol cans). It is used to clean metals. It is very toxic because it bonds with calcium ions in the body and makes them so they cannot be used. As an acid, it can be deprotonated to produce fluorides, which are also the salts of hydrofluoric acid.

If someone gets Hydrofluoric acid on them, medical attention is necessary, as just small amounts are very toxic.

USES :
This acid is most commonly used for industrial purposes. It is used in:
Computer screens manufacturing 
Fluorescent bulbs 
Glass etching 
High octane gasoline manufacturing 
Some household rust removers
