化学是在原子、分子水平上研究物质的组成、结构、性质及其应用的一门基础自然科学。这就决定了电解质相关概念在中学化学课程中处于至关重要的地位,它涉及物质的分类、质量守恒、电荷守恒、化学平衡、电化学基础、离子反应及方程式、溶液酸碱性、化学计算等多个核心概念,每一个核心概念并不是一次性地全部完成教学,而是形成了概念系列,即“电解质概念群”。 Chemistry is a fundamental science that studies the composition, structure, properties and applications of matter at the atomic and molecular levels. This determines the concept of electrolyte is crucial in the chemistry curriculum of secondary school, which involves material classification, conservation of mass, conservation of charge, chemical equilibrium, electrochemical basis, ionic reactions and equations, solution pH, chemical calculation And many other core concepts, each of the core concepts do not complete the teaching all at once, but formed a series of concepts, namely “the concept of electrolyte group.”
