氧化还原反应是中学化学重要的知识点,它与元素化合物、离子反应、有机化学、电化学等都有较强的联系,也是每年高考必考的重点内容.在复习时要抓住以下几个方面:一、守恒思想要牢记在氧化还原反应中,氧化剂得电子,还原剂失电子,氧化剂得到的电子总数与还原剂失去的电子总数相等,即电子得失守恒.利用电子得失守恒可以进行氧化还原反应的配平和计算.二、转移方法灵活用氧化还原反应的本质是电子的转移,电子转移有两种
Redox reaction is an important point of knowledge of secondary chemistry, it is with the elemental compounds, ionic reactions, organic chemistry, electrochemical and so has a strong connection, but also the annual exam will be the key content. In the review to seize the following Aspects: First, keep in mind the idea of conservation Redox reaction, the oxidant electrons, reducing agent loss of electrons, the total number of electrons obtained by the oxidant is equal to the total number of electrons lost by the reducing agent, that is, the electronic gains and losses. Use of electronic gain and loss can be redox The reaction of the balance and calculation. Second, the flexible transfer method Redox reaction is the essence of electron transfer, there are two kinds of electron transfer
