摘要：

结合移动互联网技术，开发了一款针对重金属离子化学性质的教学app，以解决元素化学教学中重金属化合物知识点繁杂零散、反应方程式多、讲授枯燥、学生需要死记硬背的问题。该款app让学生得以直接观察到重金属离子与碱、常见阴离子之间的反应，并经过归纳和总结，建立起化合物、反应现象与化学性质之间的联系，之后通过随机测试巩固并加深学生对知识的运用。该款app容量小，功能明确，界面简洁，操作容易，既可用于辅助无机化学元素部分的理论课教学，也可以用作实验教学项目。

Abstract:

Using mobile internet technology, a smartphone application (app) on chemical reactivity of common heavy metal ions was designed and exercised. The app enables students to access a variety of chemical reactions between heavy metal ions and bases as well as anions commonly used in chemistry laboratory, aiming at facilitating students' ability to summarize and memorize the chemical reaction characteristics of these heavy metal ions. A random quiz is then made to enhance the understanding and using of knowledge. The app can be used for either in-class or laboratory teaching.
