The titration error in potentiometric precipitation titration

Talanta, 1975
The titration error can be calculated with the aid of the value of the buffer index determined at the inflection point of the titration curve when a precipitation titration is followed with an ion-selective electrode. When the precipitate is not formed ideally in the titration (i.e., is not formed under equilibrium conditions) the titration error ...

Linear potentiometric titrations

Journal of Electroanalytical Chemistry (1959), 1964
Abstract A method for graphical representation of potentiometric titration curves is proposed. It permits determination of the end-point even if the conventional potentiometric curve, pH-volume, fails to define exactly an inflection point. The limits and the possibilities of the method are discussed and some examples of practical applications are ...

Potentiometric titration of diprotic systems

Fresenius' Journal of Analytical Chemistry, 1997
The approximate nature of Gran’s method of linearization of potentiometric titration curves applied to diprotic systems has been thoroughly investigated. A function involving pH and titrant volume V (which is linearly dependent on V and becomes zero at the first equivalent point of titration of a weak diprotic base with a strong monoprotic acid) has ...

Evaluation of Automatic Potentiometric Titrator in Nonaqueous Titrations

Journal of Pharmaceutical Sciences, 1966
A procedure is reported for the evaluation of the behavior of an automatic recording titrator in nonaqueous titrations and is applied to an instrument composed of commercially available units. First, the behavior of the purely instrumental features was determined and the experimental errors were compared with calculated maximum anticipated relative ...
