Popis:	It is the composition of the bath that determines a) the nature of species adsorbed and reduced at the cathode (such as molecules of a nonaqueous solvent, perchlorate anions, metal ions, or their complexes with organic ligands) and b) the electrode reaction rate. The process is best inhibited in a range of water structure stabilization under conditions of the predominant adsorption of acetone molecules, when the discharge of electroactive species is preceded by their “constrained” dissociation during the penetration through the layer adsorbed at the cathode. The highest reduction rate was observed in the acetone structuration range, when the adsorption of perchlorate anions reaches a maximum because of the desalting effect of the mixed solvent and the selective solvation (Ψ’-effect).
