电化学属于基础理论,它是高考热点,出现率极高,也是中学阶段教学的一个难点,尤其是书写电极反应方程式难度更大。任何知识都有其相关理论并且都是相通的,让学生很好地掌握并消化这部分知识,作为高中化学教师谈下我个人的一些观点。在解题中应考虑以下原理的应用:1.电极反应方程式属于氧化还原反应,且使氧化还原反应分别被拆分在两个电极上发生反应(其中:还原剂失去e-经导线传递
Electrochemistry belongs to the basic theory, it is a college entrance examination hot spot, a high incidence, but also a difficult point in secondary school teaching, especially writing electrode reaction equation more difficult. Any knowledge has its own related theories and all are interlinked, so that students can well grasp and digest this part of knowledge, as a high school chemistry teacher to talk about my personal point of view. The following principles should be considered in solving the problem: 1. The electrode reaction equation belongs to the redox reaction, and the redox reaction is separately resolved on the two electrodes (wherein: the reducing agent loses e-
