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.

Key words: Element chemistry, Heavy metal ion, Chemical reactivity, Educational app
