Abstract

In this paper, a chemical experimental instrument was designed with a sing-chip computer. By using this instrument, the teachers instructed the students to deeply and comprehensively explore the ionization of electrolytes through the processing and analysis of the experimental data, which allow the latter to profoundly understand the factors influencing the ionization of electrolytes, the variations during ionization process, and the concept of ionization. Besides, based on the evaluation of the students’ exploration activities, the teachers can further improve their experimental and core attainments in chemistry.
