The titration curve between the weak acid and strong base(KOH) best represented by the figure C. For the titration of weak acid and strong base pH at the equivalence point is always greater than 7. So at the equivalence point pH greater than 7 is only represented by figure C.

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...
