氧化还原反应是重要的化学反应类型,不仅涉及物质的化学性质,而且与能源(各种电池)、工业生产(金属的冶炼、氯碱工业、电镀等)有密切关系,因此受到重视。是历年高考的必考内容,题型主要是选择题和填空题。分析近几年高考氧化还原反应的有关内容约占总分的20%左右,其高考命题的热点是:1.氧化剂和还原剂、氧化产物和还原产物的判断及粒子氧化性、还原性强弱的比较。2.判断氧化还原反应发生的可能性,写出并用化合价升降法
Redox reaction is an important chemical reaction type, not only related to the chemical properties of the material, but also with the energy (all kinds of batteries), industrial production (metal smelting, chlor-alkali industry, electroplating, etc.) are closely related, so attention. Is the compulsory examination content of the calendar year, the main types of questions is the multiple choice and fill in the blank question. Analysis of college entrance examination in recent years, the contents of the redox reaction accounts for about 20% of the total score, the college entrance examination hot topics are: 1. Oxidants and reducing agents, oxidation products and reduction products to determine and particle oxidation, reducing strong Comparison. 2. Determine the possibility of redox reactions, write and use valence lift method
