一般化学书籍中,复分解反应里酸、碱和盐的当量与氧化还原反应里氧化剂和还原剂的当量在叙述上是有区别的。初学化学者容易认为这二者在本质上是不同的。其实不然,二者的本质是一致的,均是电荷的偏移或传递,可以统一起来。现在介绍一种克当量的新的表达方式,可以达到这个目的。 In general chemistry books, the equivalents of acids, bases and salts in the metathesis reaction differ from the equivalents of oxidizers and reductants in the oxidation-reduction reaction. Beginner chemists tend to think that the two are fundamentally different. In actual fact, the nature of the two is the same, are the offset or transfer of charge can be unified. Now introduce a gram of new expression, can achieve this goal.
