Illustration of several common electrolysis reaction manifolds: (A) divergent paired electrolysis, (B) parallel paired electrolysis, (C) convergent paired electrolysis, (D) sequential paired electrolysis (domino electrolysis), (E) anodically coupled electrolysis (F) cathodically coupled electrolysis, (G) sequential anodic electrolysis, and (H) sequential cathodic electrolysis. [All redox events are shown as single electron transfer events but redox events involving more than one electron also fall into these categories].
