Hydrofluoric Acid
chemical formula HF, hydrofluoric acid a relatively strong acid mainly used to etch silicon dioxide. Hydrofluoric acid is commonly sold as a 49% solution and has a density of 1.17Kg/L. Fluorine is not only toxic but may be absorbed through the skin without immediate evidence of irritation and later react with the calcium in bones and or poison the person exposed to the chemical. | ||||

hydrofluoric acid
hydrofluoric \hy`dro*flu*or"ic\ (?), a. [hydro-, 2 + fluoric.] (chem.) pertaining to, or containing, hydrogen and fluorine; fluohydric; as, hydrofluoric acid.
hydrofluoric acid
(chem.), a colorless, mobile, volatile liquid, hf, very corrosive in its action, and having a strong, pungent, suffocating odor. it is produced by the action of sulphuric acid on fluorite, and is usually collected as a solution in water. it attacks all silicates, as glass or porcelain, is the agent employed in etching glass, and is preserved only in vessels of platinum, lead, caoutchouc, or gutta-percha.

Hydrofluoric acid
Hydrofluoric Acid is a solution of hydrogen fluoride in water. Together with hydrogen fluoride, hydrofluoric acid is a valued source of fluorine, being the precursor to numerous pharmaceuticals, diverse polymers (e.g. Teflon), and most other synthetic materials that contain fluorine. Hydrofluoric acid is best known to the public for its ability to dissolve glass by reacting with SiO2, the major component of most glasses. This dissolution process can be described as follows:
- SiO2(s) + 4HF(aq) → SiF4(g) + 2H2O(l)
- SiO2(s) + 6HF(aq) → H2[SiF6](aq) + 2H2O(l)
