Selected Constants: Oxidation-reduction Potentials of Inorganic Substances in Aqueous Solution presents tables that will aid chemists in finding the best or most probable value of the normal or formal oxidation-reduction potential of oxidation-reduction systems. The book first presents numerical calculations that show the degree of oxidation and real oxidation-reduction systems, including the value of the potential, temperature, nature and composition of the medium, and the method of determination used. The text then takes a look at the choice of data, as well as intensity/potential curves and potentiometric determinations. The table of oxidation-reduction potentials showing the redox system, medium, method, and references is presented. The literature references starting from 1900 until 1967 are also tabulated. The publication is a dependable reference for chemists and readers interested in the oxidation-reduction potentials of inorganic substances in aqueous solutions.
