近几年高考对氧化还原反应的考查,以生产、生活、社会中的实际问题为载体,考查氧化还原反应的基本概念、氧化还原反应的配平、氧化性还原性强弱比较、氧化还原反应的计算以及在科学探究与电化学等方面应用.解答氧化还原反应试题的策略要注意两点:首先,要 The examination of redox reactions in the college entrance examination in recent years has taken the practical problems in production, life, and society as the carriers to examine the basic concepts of redox reactions, the balancing of redox reactions, the comparison of the strength of oxidative reduction, and the redox reaction. Calculations and applications in scientific inquiry and electrochemistry, etc. The strategies for answering redox questions should pay attention to two points: First,
