Abstract Using copper wire as electrode, sodium polyacrylate (a super absorbent polymer) and ammonia solution as electrolyte, this paper designed the electrolysis experiments. Experimental phenomena were clearly observed in the electrolysis process: the dissolution of anode copper, copper ion moving from the anode to the cathode and the precipitation of copper on the cathode. This experiment had advantages of manifesting the principle, simple, obvious phenomena, safe and green.
