ON THE CURENT DENSITY AND OVERTENSION SIGNS IV. THE CASE OF THE TRANSFER OF TWO IONS OF THE SAME CHARGE ACROSS THE ITIES IN OPEN CIRCUIT CONDITION
Journal Title: Analele Universitatii din Bucuresti. Chimie - Year 2009, Vol 18, Issue 2
Abstract
For a spontaneous electrode reaction the entropy production and the current density across the electrodic interface and the overtension under which the electrode reaction occurs are intimately linked. From this relationship, considering only the sign convention for the anodic and cathodic overtension, the signs of the anodic and cathodic current densities, in a galvanic cell and in an electrolysis cell, could be deduced. No other convention, except the completely accepted overtension convention and the physical convention for current, is made. The charge transfer through the ITIES could be treated by electrodic concepts as an electrode reaction (at single- or multi-electrode). A di-electrode of transfer of two ions having the same type of charge is investigated in open circuit conditions.
