金属活动性顺序的运用是初中化学的重点、难点,也是历年中考的热点。它不仅可以考查学生对知识点的掌握情况,也考查了学生灵活运用知识的能力。因此,对金属活动性的灵活掌握和正确使用对学生至关重要。金属具有一些共性,如大多数金属能被氧气氧化,但金属也存在差异性,而金属活动顺序表就体现了金属的异性。下面我将从以下几个方面对金属活动性的运用进行分析总结。一、一般运用(一)判断金属是否与酸发生置换反应,生成氢气。这是金属 The use of the order of metal activity is the focus of junior high school chemistry, the difficulty, but also the hot spot in the calendar year. It not only examines students ’mastery of knowledge points, but also examines students’ ability to apply knowledge flexibly. Therefore, flexibility and proper use of metal mobility are of crucial importance to students. Metals have some commonalities, such as most metals can be oxidized by oxygen, but the metal is also different, and metal activity order table reflects the opposite sex of the metal. Below I will be from the following aspects of the use of metal activity analysis and summary. First, the general application (a) to determine whether the metal replacement reaction with the acid to generate hydrogen. This is metal
