摘要

为了证明在无色溶液中的化学反应，选择了固体氧化铟通过溶液相转变为金属铟。一个演示描述了使用In2O3作为起始材料和酸性溶液作为溶解介质。此外，还展示了金属的胶结沉积反应。这个演示有助于培养学生的化学思维，并使小学生和大学一年级的学生参与化学。所得的铟可用于其他实验。此外，我们在这次演示中获得了干净的、可销售的金属。

Demonstration of the Indium Oxide Conversion to Indium Metal

To demonstrate the chemical reactions in colorless solutions, the transition of solid indium oxide into metallic indium through the solution phase was chosen. A demonstration describes using In₂O₃ as the starting material and an acid solution as the dissolving medium. In addition, the reaction of metal deposition by cementation is shown. This demonstration helps develop chemical thinking in students and engages schoolchildren and first-year college students in chemistry. The resulting indium can be used in other experiments. In addition, we obtained clean, marketable metals in this demonstration.

期刊介绍： The Journal of Chemical Education is the official journal of the Division of Chemical Education of the American Chemical Society, co-published with the American Chemical Society Publications Division. Launched in 1924, the Journal of Chemical Education is the world’s premier chemical education journal. The Journal publishes peer-reviewed articles and related information as a resource to those in the field of chemical education and to those institutions that serve them. JCE typically addresses chemical content, activities, laboratory experiments, instructional methods, and pedagogies. The Journal serves as a means of communication among people across the world who are interested in the teaching and learning of chemistry. This includes instructors of chemistry from middle school through graduate school, professional staff who support these teaching activities, as well as some scientists in commerce, industry, and government.
