WebWhen the amount of acid = amount of base, the pH = pKa. When a small amount of strong acid is added, it reacts with the conjugate base of the buffer system, converting it to the weak acid of the buffer system. Then the weak acid concentration increases, the conjugate base concentration decreases, and the pH drops slightly at most.
