The anodic decomposition of copper(I) N-methylhexamethylenetetramine bromide

Abstract

The process occurring at a platinum anode in contact with the copper ion conductor, cuprous N-methylhexamethylenetetramine bromide, has been investigated. It appears that at potentials positive to 500 mV (w.r.t. the Cu/Cu + electrode) anodic oxidation of cuprous ion to cupric ion occurs. Analysis of the current—time transients indicates that at short times the process is diffusion controlled. The steady-state currents obeyed the Tafel relation, the graph having a slope of 55 mV decade −1. The experimental results appear to be consistent with a mechanism involving a reversible charge transfer reaction followed by the diffusion of the cupric ions into suitable lattice sites.
