WebJun 9, 2024 · The H–Br bond is therefore weaker than the H–Cl bond and HBr is thus a stronger acid than HCl. Why HF is a weak acid class 9? Hydrofluoric acid (HF) is a weak acid mainly because it forms stable species after it dissociates. This makes HF the only hydrohalic acid that isn’t classified as a strong acid (e.g., HCl, HBr, HI). WebJun 29, 2016 · Explanation: Acidity may be related to the reaction: H A ⇌ H + + A− The stronger the acid; the further to the right lies this equilibrium. Of course, the acidity is modified by the identity of the solvent.
