氧化还原反应在生产实践中应用极为广泛,它贯穿于中学化学的全过程,是高考命题的重点和热点之一。从2005年高考试题来看,该内容的题型命制有如下特点:1.考查了从不同角度对于化学反应的分类:四种基本反应类型和氧化还原反应与非氧化还原反应。【例1】(2005年北京卷)将足量稀盐 Oxidation-reduction reaction is widely used in production practice. It runs through the whole process of middle school chemistry and is one of the focal points and hotspots of the college entrance examination proposition. From the 2005 examination questions, the content of the title system has the following characteristics: 1. Examined the classification of chemical reactions from different perspectives: four basic reaction types and redox reactions and non-redox reactions. [Example 1] (Beijing Volume, 2005) will be ample amount of diluted salt
