WebAug 21, 2024 · Hydrochloric acid is therefore a strong acid. An acid is strong if it is fully ionized in solution. Hydrobromic acid and hydriodic acid as strong acids Hydrogen … WebA weak base is analogous to a weak acid. Unlike strong bases that contain OH- and dissociate in water, the most common weak bases produce OH- by accepting a proton from water and ionizing water to form OH- according to the general equation: B(aq) + H2O(l) ∆ BH+(aq) + OH-(aq) In this equation, B is a generic symbol for a weak base. WebHF is a weaker acid because the strength of an acid is determined by how completely that acid will dissociate. Since the bond between HF is stronger than the bond between HCl, HCl will more completely dissociate which makes it a stronger acid. Why is HF an acid? shower ear caps

WebWhen a weak base and a strong acid are mixed, they react according to the following net-ionic equation: B (aq) + H₃O⁺ (aq) → HB⁺ (aq) + H₂O (l). If the acid and base are equimolar, the pH of the resulting solution can be determined by considering the equilibrium reaction of HB⁺ with water. If the base is in excess, the pH can be ... WebAqueous solutions of HF are called hydrofluoric acid. When dilute, hydrofluoric acid behaves like a weak acid, unlike the other hydrohalic acids, due to the formation of hydrogen-bonded ion pairs [ H3O+ ·F − ]. However concentrated solutions are strong acids, because bifluoride anions are predominant, instead of ion pairs.
