Quizplus · Accepted Answer

If the battery connections were suddenly reversed, the gold electrode would become the cathode and would begin to attract the gold ions present in the solution, resulting in gold electroplating onto the gold electrode. Therefore, gold ions in solution would begin to electroplate onto the gold electrode.
