“金属活动性顺序”的内容是中学化学的重点内容,也是中考和高考的热点内容之一。金属活动性顺序是金属化学性质的重要组成部分,从具体的知识点来看,主要由置换反应、典型金属与酸和某些盐溶液的反应、金属活动性顺序表及金属活动性以及应用等内容构成;内容涉及到很多化学实验,是考试常考的热点。因此,灵活掌握这一部分相关的知识非常重要~([1])。但是在实际的教学过程中我们常常存在许多误区,这给学生在学习 “Metal activity order ” content is the focus of secondary school chemistry, but also one of the hot spots in the entrance exam and college entrance examination. The sequence of metal activity is an important part of the chemical properties of the metal. From a specific point of view, it is mainly composed of displacement reactions, reactions of typical metals with acids and some salt solutions, metal activity sequence tables, metal activities, applications, etc. Content composition; content involves a lot of chemical experiments, exams are often hot. Therefore, it is important to have a flexible grasp of this part of the knowledge ~ ([1]). However, in the actual teaching process, we often have many errors, which give students a chance to learn
