    Acid-Base Titrations

    Weak Acid-Strong Base Titrations
  • At the equivalence point, all the acetic acid has been consumed and all the NaOH has been consumed. However, C2H3O2- has been generated.
    • Therefore, the pH is given by the C2H3O2- solution.
    • This means pH > 7.
      • More importantly, pH ? 7 for a weak acid-strong base titration.
  • After the equivalence point, the pH is given by the strong base in excess.
