金属活动性顺序的应用在初中化学知识中占有重要地位,一直备受中考命题者的喜爱,在每年的中考试题中肯定“亮相”。作为中考必考知识,学生必须牢记并理解、掌握其应用。下面就金属活动性顺序的应用在中考中常出现的题型加以剖析,并归纳其解题方法。一、判断金属与酸溶液(或盐溶液)能否发生置换反应例1(2013·天津)已知金属锰在金属活动性顺序中位于铝和锌之间。下列化学反应不能发生的
The application of the sequence of metal activity plays an important role in the chemistry knowledge of junior high school. It has always been loved by senior senior high school entrance exam candidates and is certainly “debuted” in the annual middle school exam questions. As the entrance exam must knowledge, students must keep in mind and understand, to master its application. The following order of the activities of the metal in the examination often appear in the questions to be analyzed and summed up the problem-solving methods. First, to determine the metal and acid solution (or salt solution) can occur replacement reaction Example 1 (2013 · Tianjin) is known metal manganese in the metal activity sequence between aluminum and zinc. The following chemical reaction can not occur
