Ionic Oxidation — Reduction Reactions

  • E. T. Denisov


The exchange of an electron between two ions of a given metal that differ only in charge (e.g., between Fe2+ and Fe3+) is studied mainly by the isotope method (IM). A radioactive isotope of one of the ions (e.g., Fe2+) is introduced into the system being studied, samples are taken at predetermined time intervals, one of the ions is precipitated, and the radioactive isotope content of the precipitate is determined. The kinetics of conversion of the metal isotope from one state to the other is used to determine the rate constant for electron transfer from one ion to the other. Control experiments are run to check the isotope exchange taking place during precipitation and separation of the ions.
