【摘要】 四大平衡包括酸碱平衡、沉淀溶解平衡、氧化还原平衡和配合物解离平衡，它们是大学基础化学的重要组成部分。针对四大平衡之间的联系，从电化学角度出发，利用电化学方法计算非氧化还原反应的平衡常数，通过多种方法开拓学生的科学思维能力，旨在帮助学生巩固理论知识，加以灵活运用，做到举一反三、触类旁通，提高学习效率，加深对化学基本原理的理解和掌握。更多还原

【Abstract】 The four major equilibria include acid-base equilibrium, precipitation dissolution equilibrium, redox equilibrium and complex dissociation equilibrium.They are an important part of basic chemistry in universities.In view of the relationship between the four equilibria, from the perspective of electrochemistry, use electrochemical methods to calculate the equilibrium constant of non redox reaction, and develop students ’ scientific thinking ability through a variety of methods, in order to help students consolidate theoretical knowledge and apply it flexibly, so as to raise learning efficiency and deepen their understanding and mastery of the basic principles of chemistry.更多还原
