WebIf a strong acid didn’t have a weak conjugate base, then it couldn’t be 100% ionised, so it wouldn’t be a strong acid. The conjugate base of a strong acid must be a weak base. … WebAug 14, 2024 · This particular case is unusual, in that the cation is as strong an acid as the anion is a base (pKa ≈ pKb). Consequently, the two effects cancel, and the solution remains neutral. With salts in which the cation is a stronger acid than the anion is a base, the final solution has a pH < 7.00.
