Linear titration plots with ion-selective electrodes.
A computational method for simultaneous determination of the equivalence volume and the Nernstian slope of an ion-selective electrode is described. Treatment of data from linear titration and standard addition procedures is simplified by the use of equal additions of standard solution. Equivalence volumes and concentrations were determined with errors of 0.5-2% by the proposed method.
