influence of electrolyte ion adsorption on the derivative of potentiometric Titration Curve of oxide suspension theoretical analysis
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2004Co-Authors: Robert Charmas, Piotr Zarzycki, Benedicte Prelot, Fabien Thomas, Frédéric Villiéras, Wojciech PiaseckiAbstract:The theory based on the 1-pK triple layer model of the oxide/electrolyte interface is used to obtain the derivative of a proton adsorption isotherm. The present approach is much more rigorous and complex from a physical point of view compared to our previous paper [J. Phys. Chem. B. 106 (2002) 13280]. In the present work we take into account adsorption of inert electrolyte ions. Also, the present approach takes into consideration the local surface heterogeneity. The aim of this work is not to propose new surface model, but to develop a theoretical basis for obtaining of proton affinity distribution from the derivatives of a potentiometric Titration Curve. We demonstrate how including of electrolyte ion adsorption influences on the shape and behavior of the local derivatives of potentiometric Titration Curves. The influence of the other parameters is also thoroughly investigated. It was found that complete description of the derivative of surface charging Curve requires a high number of parameters. Therefore, it is difficult to adopt the obtained peaks for unambiguous decomposition of experimental derivative of a Titration Curve onto the parts coming from different patches of the surface.

Explicit expressions of the general form of the Titration Curve in terms of concentration: Writing a single closed-form expression for the Titration Curve for a variety of Titrations without using approximations or segmentation
Journal of Chemical Education, 1993Co-Authors: Robert De LevieAbstract:Explicit expressions of the shape of a Titration Curve can provide insight into the feasibility of the Titration and into the conditions needed for a sufficiently sharp endpoint. They also allow one to design appropriate algorithms to evaluate Titration Curves and allow equilibrium constants to be extracted from them.

A simple expression for the redox Titration Curve
Journal of Electroanalytical Chemistry, 1992Co-Authors: Robert De LevieAbstract:Abstract Titration Curves are often discussed in piecemeal fashion: one approximate description for the part before the equivalence point, a different approximation for the part beyond this point and, finally, yet another formula for the equivalence point itsell We use examples of some simple redox Titrations to illustrate that it is not really necessary to make the customary approximations, because the entire redox Titration Curve can be described exactly as the simple ratio of a formation Curve and a dissociation Curve.
