Abstract: | Among all straight lines originating from one point and intersecting the titration curve three times, there is only one to be bisected by the inner point of intersection or to be divided in proportion to asymmetry factors. This point is to be considered as a more correct approximate value of the equivalence point than that obtained by previous methods. Practicable results are available, because in this way the qualities of asymmetrical titration curves can be taken into consideration. The asymmetry factors can be calculated and taken from tables or can be determined experimentally. |
