Abstract : It has been shown previously that the potential of the Am(III)-Am(IV) couple in acid solution is more negative than -2.0v. The work described in this paper was undertaken for the purpose of evaluating the magnitude of the potential more precisely. It seems scarcely necessary to remark that an extensive correlation of the chemical properties of an element is possible when its oxidation potentials are known The chemistry of americium possesses special interest in that it is the first of the transuranium elements in which the stability of the tripositive state is comparable to that observed for some of the lanthanide elements.
