Abstract Based on the knowledge of complexes and the actual yellow color of industrial hydrochloric acid, the three driving tasks of “exploring the reason of yellow color of industrial hydrochloric acid”, “exploring inner boundary ionization of complexes” and “optimizing the hydrolysis equilibrium experiment in teaching materials” were completed. This paper used experimental inquiry to solve cognitive conflicts, trigger deep thinking and learning, and improve core qualities such as “scientific inquiry and innovation consciousness”, “evidence reasoning and model cognition”, “macro identification and micro analysis”, “change concept and balance thought”.
