Copper Chemistry

Cover 

Reactions in gels help make a chemical process visual by slowing down the reaction rate, which allows students to observe a reaction process in detail. In Experimenting with a Visible Copper–Aluminum Displacement Reaction in Agar Gel and Observing Copper Crystal Growth Patterns To Engage Student Interest and Inquiry, Xinhua Xu, Meifen Wu, Xiaogang Wang, Yangyiwei Yang, Xiang Shi, and Guoping Wang describe an experiment in which the reaction process of copper–aluminum displacement in agar gel was observed at the microscopic level with a stereomicroscope. As shown on the cover, pine-like branches of copper crystals growing from aluminum surface into gel at a constant rate were observed. Students were asked to make hypotheses about the pattern formation and to design new research approaches to prove their hypotheses. Using this method, students carry out an experiment based on a specific chemical equation while also encountering the concepts of crystal growth and microcells through dramatic images of real-time change and visible crystal growth.
