The oxygen absorption corrosion experiment of iron is proposed in the "Chemistry Curriculum Standard" as an activity suggestion. It is a must-do experiment in middle school chemistry in the electrochemical learning section. The content of this experiment exists in both the old and new textbooks of the People's Education Edition, which is enough to show that it is used in middle school chemistry. important position in. However, the experimental phenomenon is not obvious, the observation time is long, and it is inconvenient for classroom teaching. In order to make the experimental phenomenon more obvious and the observation time shorter, this study has improved the experiment and carried out literacy teaching based on real situations.
