摘要: 基于向大一学生开设的“电解-量气法测定阿伏加德罗常数”实验，设计了Cu₂O的电化学合成及量气法测定阿伏加德罗常数一体化实验，该实验巧妙地融合了元素化学实验中有关Cu₂O的制备及性质实验内容。一次电解完成两个实验，节约电能，节省时间。Cu₂O的电化学合成及量气法测定阿伏加德罗常数一体化实验可作为一个微实验灵活穿插于大学基础化学实验教学中，对于培养大一学生的全方位思考的意识和多角度分析问题的能力以及经济、环保的理念有重要意义。

Abstract: Based on the “Electrolysis-Gasometric Determination of Avogadro’s Constant” experiment offered to freshmen, an integrated experiment was designed for the electrochemical synthesis of Cu₂O and determination of Avogadro’s constant by aerometry. This experiment ingeniously integrates the preparation and property study of Cu₂O from elemental chemistry experiments. A single electrolytic process accomplishes two experiments, save both electricity and time. The integrated experiment can be flexibly interspersed within the foundational chemistry experiment curriculum in universities. It holds great significance for cultivating students’ holistic thinking, multi-faced problem-solving abilities, as well as the concepts of economic and environmental conservation.
