Gallium is well-known for its ability to form alloys and its wide applications in semiconductors; however, it has not been investigated in detail. Therefore, we introduced a series of experiments aiming to unveil the mystery of the gallium. The experiment mainly consists of different gallium beating experiments in sulfuric acid system, alkaline system, and hydrogen peroxide system. Additionally, this experiment is safe in terms of the reagent, easy in terms of operation, and interesting in terms of phenomena, fully demonstrating the charm and profoundness of chemistry, which meets the requirements of popular science experiments. By combining small experiments on the physical properties of gallium and through reasonable designing and arranging, it is suitable for audiences of different age groups with dissimilar educational background.
- Gallium beating,
- Low melting point,
- Phased popularization of science
