Unlike other hydrohalic acids, such as hydrochloric acid, hydrogen fluoride is only a weak acid in dilute aqueous solution. This is in part a result of the strength of the hydrogen–fluorine bond, but also of other factors such as the tendency of HF, H 2O, and F anions to form clusters. At high concentrations, HF molecules undergo homoassociation to form polyatomic ions (such as bifluoride, HF 2) and protons, thus greatly increasing the acidity. This leads to protonation of very strong aci… WebAnhydrous hydrofluoric acid (AHF) Hydrofluoric acid Hydrofluoride . Product Overview .
