Unformatted text preview: curent is measured during the forward pulse and the reverse pulse and the difference is noted. d) The rotating disk electrode (RDE) usually consists of a single disk electrode surface. A ring-disk electrode contains a second ring-shaped electrode that is electrically isolated from the center disk. After an electroactive species is generated at the disk, it is then swept past the ring where it undergoes a second electrochemical reaction. f) Limiting current is the maximum current observed for an electroactive species, limited by concentration polarization. Diffusion current is the difference between the limiting current and the residual current. h) The...
