Question: In the figure below, titration curves for strong acid
with strong base and weak acid with strong base are shown. Compare
the shapes of these curves early in the titration for three
different cases: titration of a strong acid, titration of a weak
acid with a lower pKa, and titration of a weak acid with a higher
pKa. Discuss with the class why the titration curve for weak acids
increase more rapidly early in the titration than do stronger...
