1、引言英语里a mphoteric这个单词,来源于希腊语的ampho(both=双方都),在日语中译成“两性的。”这个词作为化学术语使用时意思是“兼有酸和碱两方面的性质。” 对金属元素的氧化物来说,大体上是碱性氧化物,非金属的氧化物几乎都是酸性氧化物,显示两方面性质的是两性氧化物。两性氧化物可以举出Al_2O_3和ZnO为例,像 1. Introduction The word a mphoteric in English originates from the Greek ampho (both = both) and is translated in Japanese as “bisexual.” The term “chemical term” is used in conjunction with acid and The nature of alkalis." For oxides of metallic elements, they are basically alkaline oxides, and oxides of non-metals are almost all acidic oxides, showing amphoteric oxides in both aspects. The amphoteric oxide can be exemplified by Al 2 O 3 and ZnO, like
