When Cd²+ ions are reduced to Cd atoms at the electrode surface, the concentration of Cd²+ at the surface becomes very small. Cd2+ ions from the bulk solution then moves to the electrode surface as a result of concentration gradient. The mechanism of reactant transport to the electrode surface just described is A. convection B. migration C. diffusion D. capillary action
