Draw the general titration curve for a strong acid titrated with a strong base. At the various points in the titration, list the major species present before any reaction takes place and the major species present after any reaction takes place. What reaction takes place in a strong acid– strong base titration? How do you calculate the pH at the various points along the curve? What is the pH at the equivalence point for a strong acid– strong base titration? Why? Answer the same questions for a strong base– strong acid titration. Compare and contrast a strong acid– strong base titration with a strong base– strong acid titration.
