✦ Synopsis

From the potential E, and E, of redox systems cove& by the general formulae I or 6 the empirical rule AE = A + B.l/d is &rived which describes the diffarcnce of up to four potentiaL% of one electron transfer by the longest distance d between the formal charges of the systhn and standardizal f*ocpI AandB. The wide scope of this rule is dsmonstrati as well as its us&lncss [a) to estimate up to three potentials if one is known. Ibl to detect distortion of the z-svstcm and (c) to single out tbe relevant potenti& if more potentia3s are-rn&ured than expected.
