The titration curve labelled "D" is generated by the strongest acid in the series. ✔The stronger the acid the lower its pH value at the beginning of the titration. ✔The weaker the acid the more basic the indicator needed for titration. The acid which generates curve "D" has the highest neutralization-point pH in the series. O The pk, of a titration indicator should match the pk, of the acid being titrated. In the curves shown above the stronger the acid the less NaOH required for neutralization.
