Abstract The electrochemical corrosion of iron nails is an important experiment in high school chemistry, but due to its slow reaction, it is not suitable as a classroom demonstration experiment. This article attempts to use carbon fibers to tie aluminum wires and place them in an electrolyte solution to investigate the electrochemical corrosion behavior of aluminum wires. Research has shown that this experiment can generate a large number of bubbles within 2 minutes, which is obvious, easy to operate, safe and reliable. It can be used as a case study for metal electrochemical corrosion classroom demonstration experiments and student classroom activity experiments.
