Abstract The conversion between acids represents a classic issue within non-redox reactions, illustrating the practical application of weak electrolyte ionization equilibrium and salt hydrolysis equilibrium principles in ionic reactions. This study aims to explore the impact of the acid-salt-arrow method on students' analytical capabilities concerning the transition from strong acids to weak acids, particularly in the context of the new curriculum for weak electrolyte ionization equilibrium and salt hydrolysis equilibrium. The investigation focuses on the analysis speed and depth of understanding when dealing with strong acid to weak acid transitions of varying complexities. Findings indicate that the method significantly enhances students' proficiency in distinguishing between strong and weak acids and in writing relevant equations. Moreover, the teaching approach has notably improved students' analytical speed and their capacity for quantitative reasoning.
