Potentiometric Endpoint Methods Electrochemical Titrations
The basis of potentiometry is the Nernst equation, which relates the concentration of electroactive species at the surface of an electrode (C) to the potential of that electrode (E); that is, for the reaction O + e = R where E is the formal redox potential of the electron transfer reaction. In a potentiometry experiment, the open-circuit potential (i.e., there is no measurable current through t...
متن کاملSmall-volume potentiometric titrations: EPR investigations of Fe-S cluster N2 in mitochondrial complex I.
EPR-based potentiometric titrations are a well-established method for determining the reduction potentials of cofactors in large and complex proteins with at least one EPR-active state. However, such titrations require large amounts of protein. Here, we report a new method that requires an order of magnitude less protein than previously described methods, and that provides EPR samples suitable ...
متن کاملPotentiometric titrations in a poly(dimethylsiloxane)-based microfluidic device.
This paper describes a microfluidic device, fabricated in poly(dimethylsiloxane), that is used for potentiometric titrations. This system generates step gradients of redox potentials in a series of microchannels. These potentials are probed by microelectrodes that are integrated into the chip; the measured potentials were used to produce a titration curve from which the end point of a reaction ...
متن کاملPotentiometric Titrations as a Tool for Surface Charge Determination
This article summarizes methods for determining proton surface charge at mineral/water interfaces. It covers conventional experimental procedures and discusses problems with the techniques. Also it involves recommendations for obtaining reasonable and comparable results. The term "comparable results" refers to comparison between results for the same solid as obtained in different laboratories. ...
متن کاملShort Communication A GENERALIZED APPROACH FOR THE CALCULATION AND AUTOMATION OF POTENTIOMETRIC TITRATIONS Part 2. Redox Titrations
The very fast calculation procedure described earlier is applied to calculate the titration curves of complicated redox systems. The theory is extended slightly to cover inhomogeneous redox systems. Titrations of iodine or 2,6-dichloroindophenol with ascorbic acid are described. It is shown that correspondence between theory and practice is good as long as the relevant stability constants and r...
