Integrated Experiment of "Electrolytic Preparation of Cu2O and Gasometric Determination of Avogadro's Constant: Implementation, Results, and Discussion: A Micro-Experiment Recommended for Freshmen in Higher Education at Various Levels Across the Nation
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.
