氧化还原反应是一类重要的化学反应,该内容贯穿于学习化学的整个过程,是学生学习化学的重要内容,在每次考试中均会考察。同时,氧化还原反应也是一个难点,想突破这个难点,我们就要掌握氧化还原反应的一些基本规律及其应用。一、物质性质判断规律当元素化合价处于最高价态时只具有氧化性;处于最低价态时只具有还原性;处于中间价态时既具有氧化性又具有 Redox reaction is a kind of important chemical reaction, the content runs through the whole process of learning chemistry, is an important part of students learning chemistry, will be examined in each examination. At the same time, redox reaction is also a difficult point, want to break through this difficult, we must grasp some basic rules of redox reaction and its application. First, the law of judging the nature of the material When the elemental valence is in the highest valence state with only oxidation; in the lowest valence state has only reducibility; in the valence state both with oxidation and has
