氧化还原反应是高中化学的核心理论,是高中阶段同学们接触最多的反应,也是贯穿元素化合物知识的一条主线。在新高考模式下,作为必考考点的氧化还原反应,考查时往往以一个陌生的反应为载体,常与元素化合物的考点融合在一起,考查对氧化还原反应概念、物质的氧化性、还原性、电子 The redox reaction is the core theory of high school chemistry. It is the most frequently touched reaction among high school students. It is also a main thread that runs through the knowledge of elemental compounds. In the new college entrance examination model, as an Oxidation-Reduction test, the test often uses an unfamiliar reaction as a carrier, often merging with test sites of elemental compounds, examining the concept of redox reaction, oxidation of the substance, and reduction ,electronic
