摘要
根据电导率和摩尔电导率的物理意义,通过简单计算,确定了参与导电的离子数目与电解质溶液浓度或电离度之间的关系,由此分析说明了电导率和摩尔电导率与电解质浓度的关系。方法简单清晰,便于学生领会理解。
Depending on the physical meaning of electrolytic conductivity and molar conduc- tivity, the relationship between electrolytic conductivity and molar conductivity to the electrolyte concentration was analyzed by simple calculation. The relationship between the number of con- ductive ions and electrolytic solution concentration or ionization degree was determined. The method is simple and clear, so that the students can understand easily and meet the teaching re- quirements.
