电子守恒原则,即反应中氧化剂得电子总数与还原剂失电子总数相等。利用电子守恒的原则,可以攻破难点,能使计算简便,解题快速,举例说明如下。
The principle of electron conservation is that the total number of electrons in the oxidant and the total amount of electrons lost in the reducing agent are equal in the reaction. Using the principle of conservation of electrons, it is possible to break through difficulties, make calculations easy, and solve problems quickly. Examples are as follows.
