氧化还原反应会考基本概念、基本规律及以电子转移为中心的有关计算,主要考查氧化性、还原性强弱的比较,电子转移的数目、简单的计算.氧化还原反应是化学中的主干知识,是高考不可回避的热点,今后还会推出更新的题型,要特别关注氧化还原反应规律在生产生活中的应用,在高科技成果中的应用.一、理清氧化还原反应基本概念间的相互关系二、氧化还原反应的三大基本规律及应用1.守恒规律(1)三大守恒1质量守恒:反应前后元素的种类、原子的数目和质量
Redox reaction will test the basic concepts, basic rules and electronic transfer as the center of the calculation, the main test oxidation, reducing the strength of the comparison, the number of electron transfer, simple calculation.reduction reaction is the backbone of chemistry knowledge, Is the entrance examination unavoidable hot spots, the future will be introduced updated questions, with particular attention to the law of redox reaction in the production and application of life, in the application of high-tech achievements.First, clear the basic concepts of redox reaction between Relationship two, the three basic rules of redox reaction and application 1. Conservation Law (1) three conservation 1 mass conservation: the types of elements before and after the reaction, the number and quality of atoms
