On the accuracy of acid-base determinations from potentiometric titrations using only a few points from the titration curve

Talanta. 1977 May;24(5):303-8. doi: 10.1016/0039-9140(77)80006-4.

Abstract

There are several procedures which use only a few points on the titration curve for the calculation of equivalence volumes in acid-base titrations. The accuracy of such determinations will depend on the positions of the points on the titration curve. The effects of errors in the stability constants and in the pH measurements on the accuracy of the analysis have been considered, and the results are used to establish the conditions under which these errors are minimized.
