摘要
酸碱、沉淀溶解、氧化还原和配合物解离平衡(即四大平衡)是无机化学基础理论中的重要组成部分,本文从四大平衡存在相互影响的角度,对金属硫化物的溶解情况、配合物与沉淀的生成及氧化还原标准电极电势的计算这三个具有代表意义的问题进行了探讨,希望有助于学生建立四大平衡的整体概念,启发教师教学。
The knowledge on the four equilibrium(acid-alkali, precipitation dissolution, oxidation-reduc- tion and coordination compound dissociation) is an important part of inorganic chemistry in the basic the- ory. From the viewpoint of the interaction of four equilibrium, three representative problems(dissolution of metal sulfides, the formation of complex problems and precipitation, the calculation of redox standard electrode potential) are discussed in this paper. We hope the paper can help the students to establish the overall concept of four equilibrium and provide inspiration for teaching activities at the same time.
