The influence of H+ and OH- ion recombination within the diffusion layer on electrode reactions occurring in parallel

A. V. Sokirko and Yu. I. Kharkats

The paper provides a theoretical analysis of the electrodiffusion problem arising when cations and anions are reduced in parallel at an electrode in acidic solutions and OH- and H+ ions subsequently recombine in the Nernst diffusion layer in a homogeneous reaction. The conditions are estimated under which a limiting current of anion reduction will be realized in the system and under which hydrogen ions start to be directly involved in the electrode process.
