Abstract Within the authentic context of “acidification and deacidification methods of paper relics”, a project-based teaching approach on “hydrolysis of salts” was implemented. By establishing four specific project tasks:“Analyzing the causes of acidification in paper relics” “Deacidifying the acidified paper relics” “Restoring and mounting the paper relics” and “Completing deacidification documentation for paper relics”. students are guided to actively engage in inquiry-based learning. This process enables them to grasp the concepts and principles underlying salt hydrolysis, investigate its primary influencing factors, and explore practical applications. The execution of this project not only allows students to experience the integration of chemical knowledge with cultural heritage conservation but also facilitates their advanced understanding of chemical equilibrium.
