Relaxation Theory

The paper presents the application of the relaxation theory of electrode reaction in a diffusional system. The theoretical equations derived are tested by the experimental results of a simple charge transfer reaction Fe3+ + e = Fe2+ on Pt electrode in 1M H2SO4.

The Stability

The addition of a metallic nitrate such as Zn(NO3)2, Cu(NO3)2, or UO2(NO3)2 to N2O4 solutions in aprotic media leads to the reclaiming of the NO+ species (which is considered as a catalyst for the nitration of aromatics by N2O4) as follows: [Formula: see text]. Using linear voltammetry, the study of the N2O4 reduction in the presence of metallic nitrates with a platinum electrode has allowed us to derive the equilibrium constant for reaction [1] and that corresponding to the formation of the trinitrato complexes in sulfolane according to: [Formula: see text]. The strong stability of the [Formula: see text] complexes is due to the weak solvating character of the sulfolane. This hypothesis is also confirmed by the stability constants of zinc[II] chloride complexes: [Formula: see text] in sulfolane from a potentiometric study by means of a silver chloride – silver electrode.
