Abstract In response to the difficulty in observing white precipitates in the preparation of Fe(OH)2 experiments, students were encouraged to independently innovate in the classroom and personally experience the entire process of designing experiments based on literature, verifying experiments, and ultimately obtaining a successful experimental plan. The innovative experimental plan obtained is to take a coarse iron wire into a test tube, add 6 mol/L dilute sulfuric acid, and add 40% NaOH solution to it after the bubbles are not obvious. This plan is simple, easy to operate, and has obvious phenomena, making it suitable for students to conduct group experiments. At the same time, unexpected phenomena generated during the experimental process stimulate students’ deep thinking and develop their experimental exploration ability. The innovative design process of the experiment and the analysis and solution process of unexpected phenomena have stimulated students’ innovative thinking.
