氧化还原离子方程式与电极方程式的书写是历届各省高考化学必考内容,对学生提炼题目信息、挖掘潜在条件、综合处理问题及基本功的体现等方面提出较高的能力要求。在学习过程中,我通过对比归纳总结出一种书写氧化还原离子方程式及电化学电极方程式的方法——四步法,在与班级学生的分享交流中,得到非常好的效果。模型的建立如表1所示。
The formula of redox ion and equation of the electrode is the compulsory part of all provincial college entrance examination chemistry, and puts forward higher ability requirements for the students to extract the topic information, explore the potential conditions, comprehensively deal with problems and the manifestation of basic skills. In the process of learning, I summed up by writing a method of writing equations of redox ion and electrochemical electrode - four-step method, in the exchange and class students to share very good results. The model is established as shown in Table 1.
