The use of homogeneous electrochemical catalysis (HOMEC) enabled direct evaluation of the role of collective factors X. Already the differences between the products of direct and HOMEC electrolysis x dir , x hom at once indicating the presence of collective effects, ECS and/or VCS. Changing the HOMEC´s contribution, near electrode tomography (NELTO), opens another fundamentally new possibility -the study of the dependence of x on the distance L from the electrode surface. So far, the change of two collective characteristics X with distance L, viscosity η and dielectric constant ε, has been demonstrated, on specific examples in the review; here we can add also the medium´s magnetic permeability, with the dependence μ =F(L).
