It would seem to me that this should be an extremely polar bond, almost ionic in nature. So why doesn't this acid completely dissociate in water? While fluorine is the most electronegative element, you also have to consider the fact that it hydrogen bonds, where other halide acids do not. It can hydrogen bond to itself, as well as to water. Since the Hs in HF are tied up in hydrogen bonding, H+ is not free to move about the solution to affect pH.The hydrogen bonding also stabilizes the H-F bond significantly. So despite the...
