基于"双极"技术的电势-pH图解析与电化学性能优化基础实验OA

This study addresses the pedagogical challenges associated with Pourbaix diagrams in inorganic chemistry by incorporating bipolar membrane technology to develop a visualized experimental approach.Utilizing sodium alginate as the raw material,we fabricated a bipolar membrane and constructed an electrochemical cell to systematically investigate the effects of pH and overpotential on cell voltage.The experiment employs a blended online-offline teaching methodology with tiered experimental modules,facilitating interdisciplinary knowledge integration.Characterized by operational simplicity,reagent safety,and cost-effectiveness,this approach enhances students'theoretical understanding and innovative thinking,making it particularly suitable for undergraduate chemistry education.
