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...

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...
