- Аннотация: It is the aim of this work to investigate the specific adsorption of Cl** minus ions on mercury from mixed aqueous NaF plus NaCl solutions (c equals 0. 1 M) in order to subsequently compare the experimental results with conclusions of the new theory of ionic adsorption. The mercury/aqueous solution interface was selected because it offers the possibility to attain the highest accuracy in the impedance measurements. It follows from theoretical considerations that the most sensitive region for a test of theoretical conclusions is that of low coverages, GAMMA //1, and of low ionic strength, c, of the solutions. It is shown that in the cathodic region one finds a marked decrease of W//a//d//s**o**o, evidently because of weakening of the adsorbate-adsorbent bond due to repulsion of the adsorbed ions by the field of an electrode of like charge, which is similar to the effect found in I** minus ion adsorption on bismuth or because of a change in the solvating properties of the solvent in the compact layer which may occur with changing charge of the electrode. The results obtained show that the new theory of ionic adsorption yields an adequate description of data for Cl** minus ion adsorption on mercury from mixed aqueous electrolyte solutions having a total solution concentration of c equals 0. 1 M.
