    Acid-Base Titrations

    Weak Acid-Strong Base Titrations
  • Consider the titration of acetic acid, HC2H3O2 and NaOH.
  • Before any base is added, the solution contains only weak acid. Therefore, pH is given by the equilibrium calculation.
  • As strong base is added, the strong base consumes a stoichiometric quantity of weak acid:
    HC2H3O2(aq) + NaOH(aq) ? C2H3O2-(aq) + H2O(l)
