氧化还原反应方程式的配平是高中的重点和难点之一,现行高中化学课本(第一册)将氧化还原反应的基础知识编排在第一章第三节,而把氧化还原反应方程式的配平编排在第六章第五节,有的中学化学教师认为这样的安排给实际的教学带来困扰,会使教学缺乏系统性,降低了教学要求,而把氧化
The balancing of the redox reaction equation is one of the key and difficult issues in high school. The current high school chemistry textbook (Volume 1) lays the basic knowledge of the redox reaction in Chapter 3 of Chapter 1 and arranges the trim equation of the redox reaction equation. In Chapter 5, Section 5, some high school chemistry teachers believe that such an arrangement brings difficulties to the actual teaching, which may make the teaching less systematic and reduce the teaching requirements, while the oxidation
