氧化还原反应在高中阶段的基本概念、基本理论中,占有非常重要的地位,是高中教学的重点和难点内容,同时也是历年高考命题的热点。因此,学生要打下坚实的基础,关键是高一对氧化还原反应的学习。《氧化还原反应》的学习要掌握好三关的要领,从初中的元素的化合价入手;利用元素化合价升降的这一特征,准确判断反应物中的氧化剂、还原剂;然后通过双线桥法分析电子转移的关系,解决氧化还原反应 Redox reaction in the high school phase of the basic concepts, basic theory, occupy a very important position is the focus of high school teaching and difficult content, but also over the years the hot topic college entrance examination. Therefore, students should lay a solid foundation, the key is to learn a high redox reaction. “Redox reaction” learning to master the essentials of the three off, starting from the elementary valence of the elements; the use of elemental valence of the rise and fall of this feature, accurately determine the reactants oxidant, reductant; and then by the two-lane bridge analysis The relationship between electron transfer, to solve the redox reaction
