摘要: Abstract The kinetics of Ni2+ deposition at the mercury electrode, from non-complexing electrolytes in mixed water methanol solvents has been investigated. rate this reaction, whole composition range, large overpotentials is controlled by a limiting “chemical” process. constants process when plotted as function solvent display relationship similar to those observed for organic, bidendate ligands substitution reactions, believed Ni(II)-solvent bond rupture. Hence, discharge can be identified slow dissociation step. These results confirm mechanism dischrage already proposed Gierst and Dandoy on basis investigations performed aqueous solutions.
