In the new textbook of the People's Education Press (2019), the reaction between iron and water vapor is an important experiment in high school chemistry, which is strong evidence of iron as an active metal. However, after demonstrating the experimental device in the textbook, it was found that the success rate of this experiment is not high, and there are problems such as easy tube cracking, insufficient water vapor, incomplete reaction, and insufficient hydrogen generation. Based on the core competencies of chemistry, introducing an induction heater into the experiment, and adding a self-made reaction device and impurity removal safety bottle to achieve integration of the experiment, achieving the goal of simplicity, safety, obvious phenomena, and efficiency and time saving.
