The graph below shows the titration curves for two monoprotic acids.
The graph below shows the titration curves for two monoprotic acids. What is the approximate pH at the equivalence point of each titration? 40.0 mL of each acid was titrated with 0.100 M base. Which acid is less concentrated? Estimate the pK_a of the weak acid.

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...
