No, strong acid-strong base titrations do not have a buffer region.
During the titration of a strong acid with a strong base, the pH changes dramatically around the equivalence point, where the amount of acid equals the amount of base. This is because strong acids and bases completely dissociate in solution. As one is added to the other, the resulting solution’s pH shifts rapidly from acidic to neutral to even slightly basic.
A buffer region typically exists in a titration involving weak acids and weak bases, where the pH changes more gradually due to the presence of an equilibrium between the weak acid and its conjugate base (or vice versa). In contrast, since strong acids and bases do not have such equilibria, there is no region over which the pH remains relatively constant while the titrant is added, hence no buffer region.
