WebThere is virtually no difference in the total HF and HCl values. The large bond enthalpy of the H-F bond is offset by the large hydration enthalpy of the fluoride ion. There is a very strong attraction between the very small fluoride ion and the water molecules. WebHF is a weak acid due to strong Coulombic attractions since the small radii of H+ and F- ions augment the difference in electronegativity and prevent the dissociation of protons (although its weak acidic nature is also due to the presence of hydrogen bonding).
WebHydrofluoric acid (HF) is a commonly used acid with industrial applications. It is used as a cleaning agent in the petroleum industry and glass etching. It is also one of the strongest inorganic acids known. Hydrofluoric acid is particularly lethal due to its properties both as an acid and as a metabolic poison. WebThere is virtually no difference in the total HF and HCl values. The large bond enthalpy of the H-F bond is offset by the large hydration enthalpy of the fluoride ion. There is a very …
