Abstract A series of situational questions were designed based on “polishing solution for copper products”, with the aim of exploring how concentration, temperature and acidity affect the strong oxidation of nitric acid, the instability of nitric acid as well as the storage and transportation of nitric acid. Students are expected to promote the knowledge accomplishment and implement the core literacy of chemistry via carrying out a variety of inquiry activities focusing on chemical experiments, through which students structure the knowledge of “the nature of nitric acid”, exploit the structured knowledge to evaluate the advantages and disadvantages of copper polishing solution, and put forward reasonable improvement plans for this polishing solution.
