AN ADDITIONAL ANALYSIS OF KINETIC AND ADSORPTION EFFECTS IN CESIUM SALT-SOLUTIONS AT THE MERCURY WATER INTERFACE

An additional analysis of the kinetic and adsorption effects occurring at the mercury electrode in aqueous solutions of cesium salts was performed in terms of Fawcett's model, which assumes that there are two different positions of the outer Helmholtz plane (x2' and x2") for different electrolyte ions. It was shown that the experimental shift of the potential of zero charge found for the Hg electrode in aqueous CsF solutions is much higher than the values of DELTA-E(q = 0) calculated for whatever value of the dielectric constant, epsilon-1, in region x2'x2". It was also shown that the version of Fawcett's model assuming a lower value of epsilon-1 is internally inconsistent owing to the effect of image forces.
