氧化还原反应是初中化学的一个基本概念。学好这一概念，要做到“三要”。一、要明确墓求初中化学里，只要求从得失氧的角度去分析氧化还原反应，并据此找出氧化剂、还原剂，判断哪种物质被氧化（发生氧化反应），具有还原性，哪种物质被还原（发生还原反应），具有氧化性。二 Redox reaction is a basic concept of junior high school chemistry. To learn this concept well, it is necessary to achieve “three things.” First, to clarify the tomb of junior high school chemistry, only from the perspective of oxygen loss to analyze the redox reaction, and to find out the oxidants, reducing agents, to determine which substances are oxidized (oxidation reaction), with reduction, which The material is reduced (reduction reaction occurs) and is oxidizing. two
