氧化还原反应是中学化学学习的主线,也是高考必考考点之一,一般以典型物质或社会实际问题为载体,以选择题或填空题的形式出现,考查学科内知识的综合能力。氧化还原反应涉及面广,学生要特别关注氧化还原反应的规律在生产生活中的应用,在最新科技成果中的应用,在新型材料和化学中的应用等。氧化还原反应高考常见题型有:求氧化产物和还原产物的物质的量之比;给出陌生的物质,判断其反应前后的化合价或判断其是否是氧化产物、还原产物;物质氧化性、还原性强弱的判断等。
Redox reaction is the main line of secondary chemistry learning, but also one of the college entrance examination sites, the typical substance or social practical problems as a carrier, to multiple choice questions or fill in the blank form, to examine the comprehensive ability of knowledge within the discipline. Redox reaction involves a wide range of students should pay special attention to the law of the redox reaction in the production and application of life, the latest scientific and technological achievements in the application of new materials and chemistry. Redox reaction college entrance examination common questions are: seeking the amount of oxidation products and the reduction of the ratio of the amount of substance; given unfamiliar substances, determine the reaction valence before or after the reaction or determine whether it is an oxidation product, reduction products; material oxidation, reduction Judgment of the strength and weakness.
