在中学化学教学中经常要利用金属活动性顺序来解释金属参与化学反应的现象。但很多有金属参加的化学反应所呈现的现象与金属活动性顺序似乎不符。这就要求教师要对金属活动性顺序的概念及其应用有深入的了解,才能给学生提供正确的解释。现行中学教科书中的金属活动性顺序表是按金属在水溶液中形成稳定的低价阳离子的标准电极电位由小而大的顺序排列而成的。它表示了金属固体在水溶液中形成水合离子的能力由 Chemistry teaching in high school often use metal activity order to explain the phenomenon of metal involved in chemical reactions. However, many of the reactions that occur with chemical reactions involving metals do not appear to be in line with the order of metal activity. This requires teachers to have a deep understanding of the concept of metal mobility and its application in order to provide students with the correct explanation. Current active secondary school textbooks in the sequence table is based on the metal in aqueous solution to form a stable low-cost cation standard electrode potential from the small and large order from. It shows the ability of metal solids to form hydrated ions in aqueous solutions
