用加合法配平复杂的氧化还原反应式在氧化还原反应复习中，常会遇到一类复杂的氧化还原反应，它们有的是由几种氧化剂或几种还原剂参加的反应，有的是由氧化还原反应和非氧化还原反应组合而成的复杂反应。配平这类反应的反应式难度大，学生不易掌握，这里介绍一种配平方法... Redox reactions with redox reactions with redox reactions often encounter a complex class of redox reactions, some of them by several oxidants or several reducing agents to participate in the reaction, some by the redox reaction and non- Redox reaction combination of complex reactions. Balancing the reaction of such reactions is difficult, difficult to master the students, here to introduce a trim method ...
