Abstract
Abstract The available spectroscopic data do not support the current theory on the nature of aqueous hydrofluoric acid: namely, undissociated HF molecules in dilute solutions (weak acid), and HF − 2 or more complex ions at higher concentrations (strong acid). A different model is proposed, involving as a dominant species ion pairs of hydorxonium fluoride H 3 O + …F − linked by an exceptionally strong hydrogen bond. This model is also more consistent with various other properties of the H 2 O-HF system.
