설명

일반 설명

Hydrofluoric acid (HF) is a strong inorganic acid that is commonly used as a source of fluorine for the production of organofluorine compounds and inorganic fluorides. It is also used as a deprotecting reagent in organic synthesis. Additionally, it is also used for breaking strong Si-O bonds to form SiF6− 2 ions in an acidic solution.
