Title: The accuracy and precision of the classical technique for locating the point of maximum slope on a potentiometric titration curve
Abstract: When it is applied to data simulating those that might be obtained in the titration of either a strong acid or a monobasic weak acid with a strong base at the same concentration, the classical-technique for locating the end-point of a potentiometric titration has a bias that is statistically indistinguishable from zero. Its precision depends on the standard error of measurement of the volume of reagent but exhibits no detectable dependence on the standard error of measurement of the pH. If the acid is strong, the precision is improved by decreasing its concentration; if the acid a weak, the precision is improved by inccreasing its pKa value or by decreasing its concentration.
