氧化还原反应的本质是电子的转移(或偏向),氧化还原反应的特征是化合价的升降,学生在必修1中已经深入的学习了氧化还原反应,为学习电化学打下了良好的基础。电化学属于氧化还原反应的范畴,因此从氧化还原反应的角度确定电化学中的电极、利用得失电子守恒进行计算、电极反应式的书写及配平等都可以迎刃而解。 The nature of the redox reaction is electron transfer (or bias), the redox reaction is characterized by the valence of the lift, the students in compulsory 1 has been in-depth study of the redox reaction, to learn electrochemical laid a good foundation. Electrochemistry belongs to the category of redox reaction. Therefore, it is very important to determine the electrochemical electrodes from the perspective of redox reaction, and use the conservation of electrons and losses to calculate.
