Abstract Faraday’s law is the quantitative basis of electrochemical theory and the first step for college students to understand modern electrochemical theory. This experiment improves the related experiments of Faraday’s law in general chemistry experiments, taking into full consideration of the difference between the chemical knowledge system of high school and university. This experiment designs two experimental sections, which are the determinations of Avogadro constant and current efficiency, introducing Faraday’s law and its application to students through the anodic oxidation process of ferrum. Based on the rich experimental phenomena, students are guided to make a smooth transition from high school chemical knowledge basis to university chemical theories, and are encouraged to think further about the connection between redox and electrochemistry on the basis of their existing knowledge through the experiments. This experiment promotes the further understanding of Faraday’s law and the redox properties of ferrum, improves the knowledge system, and enhances the interest in chemistry learning of students.
