Obviously, this is an analogy of the Hess law in thermodynamics. Equation (3.2.24) is not restricted to the case where the lowest oxidation state is a metal. Consider the reactions A + e<^B and B + e<= C (3.2.25).NET Crystal bar code generatorwith .netuse .net crystal barcode generation torender barcode for .netThe sum of these reactions yields a reaction termed disproportionation: aB (3.2.26)Bar Code barcode library with .netusing .net tocreate bar code with asp.net web,windows applicationwhere K is the disproportionation constant.

The usual dependence for n = 2 is obtained for complete disproportionation, that is K 1. With decreasing K, the E~P curve changes and at K = \ assumes the usual shape for n = 1. For small K values three inflection points appear on the curve. This situation often occurs for organic quinones. Form B is then termed the semiquinone. A typical inorganic redox system of this type involves the equilibrium between metallic copper and copper(II) ions. In the absence of a complexformer the disproportionation constant is large and a solution of Cu+ ions is very unstable. However, in the presence of ammonia, copper(I) ions are bonded in a complex, constant K decreases and the E-(3 curve exhibits three inflection points.Receive barcode for .netusing barcode encoder for vs .net control to generate, create bar code image in vs .net applications.-8 0.8 1.2 Overall oxidation degree,/3 1.6 2.0.NET ean-13 integratingon .netgenerate, create ean-13 supplement 5 none in .net projectsFig. 3.10 Dependence of the potential function v = (2F/2.3RT) [E K A,B + B,C)] on the overall oxidation degree J3 for a system with disproportionation.

The quinhydrone electrode is an example of more complex organic redox electrodes whose potential is affected by the pH of the solution. If the quinone molecule is denoted as Ox and the hydroquinone molecule as H2Red, then the actual half-cell reaction Ox + 2e * Red2" (3.2.29) is accompanied by reactions between the hydroquinone anion Red2" and the solvent.
