Adsorption of C1** minus , HSO** minus //4 and H//2PO** minus //4 ions on electrodes formed by electrodeposition of silver on thin silver or gold layer has been studied in acidic medium (mostly in 1 mol dm** minus **3 HC10//4). Potential dependence of the adsorption has been determined at low concentration of these species (c less than 10** minus **3 mol dm** minus **3). It is shown that the onset of the anodic dissolution of silver is preceded by a significant adsorption of the anions. Potential dependence of the adsorption of labelled Ca**2** plus ions was studied in alkaline medium (0. 1-1. 0 mol dm** minus **3 NaOH) at low Ca**2** plus ion concentrations. It is found that a significant adsorption occurs at low potentials where the formation of surface oxides cannot be assumed only the electrosorption of OH** minus ions is expected on the basis of literature data.
