Web1 mrt. 2024 · The simple reason hydrofluoric acid is a weak acid is because it does not completely dissociate into its ions in water (the definition of a strong acid). Initially, HF actually does dissociate almost completely: HF + H 2 O ⇆ H 3 O + + F –. However, after the acid dissociates, it participates in other reactions with itself and with water. WebAcids become stronger as the X -H bond becomes weaker, and bonds generally become weaker as the atoms get larger as shown in the figure below. The Ka data for HF, HCl, HBr, and HI reflect the fact that the X -H bond-dissociation enthalpy ( BDE ) becomes smaller as the X atom becomes larger. HF. Ka = 7.2 x 10 -4. BDE = 569 kJ/mol.

Web7 aug. 2024 · Hydrofluoric acid is usually considered a weak acid, and it is indeed weaker than the other hydrohalic acids (pKa 3.17, mid-strength). However, in high concentrations it behaves like a strong acid, because it starts to protonate itself, forming H 2 F+ cations which are much more acidic than H 3 O+, and also HF 2-anions which are a weaker base ... WebThe first step in the analysis is to consider the stability of the two hydrohalides. Clearly, the stability of HF is greater than HI as witnessed by their respective heats of formation, -65 …
