Quizplus · Accepted Answer

Reversing the battery connections would cause the current to flow in the opposite direction, which would cause the gold ions to be attracted to the gold electrode instead of the cheaper metal being electroplated. This would cause the gold ions to begin electroplating onto the gold electrode instead of the cheaper metal.
