Abstract Taking the reaction of Fe3+ and I- as an example, this paper combined the concrete primary battery with the abstract chemical equilibrium concept, and presented several knowledge points such as redox reaction, chemical equilibrium and movement, primary battery and etc simultaneously, which was helpful for students to construct systematic and structured integrated knowledge network. This paper improved the experimental equipment and the amount of reagents, determined the best conditions for the classroom demonstration of this experiment, and provided teaching suggestions for teachers' teaching.
