Abstract
A quantitative theory of the electrode surface conductance decrease caused by adsorbed ions is discussed that shows good agreement with the measured results. Conductance measurements are shown to provide a reliable measure of adsorbed ion surface concentration. The sensitivity of conduction measurements to adsorbing ions and surface free electron density changes is discussed. Changes in the adsorbed state are detected as a function of electrode potential. The conductance measurements are used to measure the ionic diffusion rate of I− through an aqueous electrolyte.Keywords
