金属活动性顺序的探讨——由一道初中化学试题引发的思考

Discussion on the Sequence of Metal Activity

列举了金属活动性顺序只能说明反应的趋势，不能说明反应速率的例子。解释了一些常见金属活泼性强，反应速率反而慢的原因。指出并举例说明了一些反应不能用金属活动性顺序来判断反应的方向。总结了在使用金属活动性顺序时应考虑的几点内容。

This paper listed some examples to explain the sequence of metal activity can only indicate the tendency of chemical reaction but not reaction rate, the causes for slow reaction rates of common active metals, and the direction of some reactions not judged by the sequence of metal activity. Moreover, summarized some considerations when using the sequence of metal activity.
