Popis: A stream of electron conductor powder (graphite, silver, and tin) was introduced to the measurement of Volta potential difference. The stream of the conductive powder was placed at the center of a vertical glass tube, while an aqueous electrolyte solution of KCl was run along the inner wall of the tube. The potential difference between the terminals of the streaming conductive powder electrode and the Ag/AgCl electrode inserted in the KCl solution was measured. From the experimental result, the real potential of the solvation of Cl− ion was determined. The values obtained by the present method were compared with the reported values based on the Kenrick method with mercury jet electrode.
