Concentration profiles near a copper cathode immersed in a 0.3 mol/L CuSO 4 aqueous solution were determined by theoretical computation and by measurement with a Jamin optical interferometer. The semi‐infinite diffusion and convective diffusion equations corrected by an experimental factor corresponded well with the experimental results.
