氧化-还原反应作为化学反应的一种类型,有其普遍性和重要性.元素的原子在构成物质时,由于外围电子的得失或共用而建立起化学键,在化学反应中随着原子的离合与重组发生键的破裂与重建.在上述过程中,键合电子的隶属关系常发生变化,因此氧化一还原反应是一种常见的反应类型.从中学化学教学内容来看许多重要元素和化合物的性质其中许多 Oxidation-reduction reaction, as a type of chemical reaction, has its universality and importance. When an atom of an element constitutes a substance, a chemical bond is established due to the gain or loss of the peripheral electrons, and the atom interacts with the atom in the chemical reaction. The breakage and reconstruction of recombination occurred. In the above process, the affiliation relationship of bonding electrons often changes, so oxidation-reduction reaction is a common reaction type. From the teaching content of middle school chemistry, the nature of many important elements and compounds are seen. Many of them
