Hydrofluoric acid (HF) is a hydrogen fluoride solution in water. A valuable source of fluorine.
Hydrofluoric acid is a very corrosive acid, especially for oxides and can dissolve glass. Because of this, they hold it in plastic containers. Hydrofluoric acid is considered a weak acid: dissolves as follows:
HF + H2O is in equilibrium with H3O + + F-
The constant equilibrium of this dissolution is very small. For this reason, most of the hydrogen fluorides are solubilised in the form of a molecule, but like methanol that can be mixed with water to any ratio. This acid is a hydroxylase of acids, and hydroxyl acids are not strong acid. Hydrogen fluoride is also highly toxic and quickly damages the lungs and eyes, and its solution in water is also highly toxic and can burn deep without pain. As a catalyst for the preparation of high octane fuels, corrosive and winding glass.
