Abstract: A study was made of ionic equilibria in solutions of iodine and pyridine in n-heptane. A significant difference was found between freshly prepared and stored pyridine-iodine solutions. The experimental data for the stored solutions were reproducible and consistent.;EMF measurements were performed on cells of the type Pt(VBAR)I(,2),KI(Cl)in Py(VBAR)(VBAR)I(,2),KI(C2) in Py(VBAR)Pt. For the proposed dissociation of the molecular complex, the degree of ionization, the equilibrium constant and the enthalpy and entropy changes were calculated. Measurements of cyclic voltammetry, UV-Vis spectroscopy and Raman spectroscopy were also made.;Conductivity and concentration cell measurements have yielded more information about the reactions occurring in the system. It is anticipated that the results of this research will increase our understanding of the formation and interaction of ionic species in organic systems and will extend the field of non-aqueous electrolytes.
