Thanks! Click to expand... Do u mean plating. I don't know that precipitation occurs. Though gas can evolve as well. Plating is always on cathode anyway Upvote 0 Downvote

A+ + e- --> A....you can think of that as going from cation (dissolved in solution) to 'solid' (no longer an ion) at the anode: A ---> e- + A+...same way of thinking, it goes from 'solid' into solution Upvote 0 Downvote
