Witryna30 gru 2024 · A very weak acid always forms a strong conjugate base. A very weak base always forms a strong conjugate acid. Note: The conjugate acid from the strong base and conjugate base from the strong acid can never function as acid and base, since, they are too weak to either react with H + and OH – ions in water solution. WitrynaIn this example, our weak base is ammonia, NH3. The conjugate acid to ammonia is the ammonium ion, NH4+. And if we have an aqueous solution of ammonium chloride, in solution, there are ammonium ions, NH4+. So we have a weak base, NH3, and its conjugate acid, NH4+. And when the two aqueous solutions are mixed, we'll have a …
