HCl is a strong acid, and CH₃COOH is a weak acid. During a reaction with a strong base, the weak acid is forced to completely dissociate (there is no weak acid molecule left intact at the equivalence point). Since it completely dissociates, the accepted value for the ∆Hrxn for CH₃COOH is about 1.9 kJ/mol less than for the HCl. Explain why this is so.

Sketch the titration curve for a weak acid titrated by a strong base. When performing calculations concerning weak acid–strong base titrations, the general two-step procedure is to solve a stoichiometry problem first, then to solve an equilibrium problem to determine the pH. What reaction takes place in the stoichiometry part of the problem? What is assumed about this reaction?

At the various points in your titration curve, list the major species present after the strong base (NaOH, for example) reacts to completion with the weak acid, HA. What equilibrium problem would you solve at the various points in your titration curve to calculate the pH? Why is pH is greater than 7.0 at the equivalence point of a weak acid-strong base titration? Does the pH at the halfway point to equivalence have to be less than 7.0? What does the pH at the halfway point equal? Compare and contrast the titration curves for a strong acid–strong base titration and a weak acid–strong base titration.
