Exploration of Electrolyte Ionization Activities with a Self-made Instrument and the Student Evaluation

Biao Zou, Guizu Ye, Zitian Hong

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.

Keywords


Ionization, Electrolyte; Experimental Instrument; Self-made Instrument
