Abstract: This study comprehensively reforms the classic physical chemistry experiment involving the determination of the ionization equilibrium constant of acetic acid via conductometry. It addresses three key limitations: insufficient support for inquiry-based learning, lack of microscopic mechanistic insight, and reliance on conventional data processing methods. The reform incorporates three main strategies: expanding experimental protocols to enhance exploratory learning, introducing theoretical calculations to elucidate microscopic mechanisms, and implementing a custom-developed WeChat mini-program for intelligent data processing. These improvements significantly elevate the project’s “high-order, innovative, and challenging” quality, presenting a practical paradigm for a novel teaching model that effectively integrates theory and experimentation.
