Why is H-F a weak acid - CHEMISTRY COMMUNITY

WebBy contrast, although hydrogen fluoride dissolves freely in water, hydrofluoric acid is only a weak acid - similar in strength to organic acids like methanoic acid. In the past, the explanation for this was often given as the very high strength of the H-F bond, which has to be broken when hydrogen fluoride forms ions. http://www.nano.pitt.edu/sites/default/files/MSDS/Acids/Hydroflouric%20Acid.pdf
