氧化还原反应是贯穿整个中学化学基本理论和元素化合物知识中的重要基础知识。在中学化学教材中它是分散和渗透在各章节循序渐进展开的。复习时应将它们加以归纳、综合,掌握其规律性,并准确地运用这些规律,解决实际问题。 Redox reactions are an important basics throughout the chemistry of elementary schools and elementary compounds. It is scattered and infiltrated in the middle school chemistry textbooks in each chapter step by step. When reviewing, they should be summed up, integrated, mastered their regularity, and accurately use these rules to solve practical problems.
