"Web9 de set. de 2024 · Acetic acid donates a proton. Similarly, when you add small amounts of strong acid (H 3 O +) to a buffer, the buffer will resist changes in its pH by sending an equal amount (stoichiometric amount) of its weak base to accept a proton from the strong acid. Once the base accepts the proton, it turns into its conjugate acid, while the strong … " - How a buffer solution maintains its ph
