一、课题第三节氧化还原反应二、教材分析1.在中学阶段的化学基本概念、基础理论知识中,氧化还原反应占有非常重要的地位,是中学化学教学的重点和难点之一。在中学化学中要学习许多重要的元素及其化合物知识、凡涉及元素化合价变化的反应都是氧化还原反应。掌握氧化还原反应的实质是认识元素及其化合物性质的基础。本节主要包括三部分内容,即氧化还原反应的概念、氧化还原反应的特征和氧化还原反应的本质。教材
First, the subject of the third section of the redox reaction Second, the textbook analysis 1 in the secondary phase of the basic concepts of chemistry, basic theoretical knowledge, redox reactions occupy a very important position, is one of the key and difficult secondary chemistry teaching. In secondary chemistry to learn a lot of important elements and their knowledge of compounds, involving changes in the valence of the elements of the reaction are redox reactions. Grasp the essence of the redox reaction is the basis for understanding the nature of the elements and their compounds. This section mainly includes three parts, namely, the concept of redox reaction, the characteristics of redox reaction and the nature of redox reaction. Teaching material
