Abstract

The series arrangement of identical electrolytic cells having copper anodes and chloride electrolyte is found to demonstrate an extremely asymmetric and reciprocally oscillating voltage drop across the series of these coupled cells. The origin of this phenomenon is attributed to the presence of different extents of cuprous oxide phase on surfaces of the anodes of different cells, in the series. Such series arrangement of multiple electrolytic cells introduces a novel phenomenon of the non-linear temporal behaviour of coupled cells. Most importantly, such configuration proves the very existence of adsorbed Cu₂O on surface of copper anode, in acidic chloride media. And hence, it signifies the important role of Cu₂O in the electro-dissolution mechanism of copper anode, even at lower pH values.
