摘要:应用电导率仪在298 K下测定4种稀土氯化盐ErCl3,DyCl3,NdCl3和YCl3在极性水溶剂中的电导率,利用公式计算稀土氯化盐的摩尔电导率,并讨论了浓度对稀土氯化盐水溶液电导率和摩尔电导率的影响,稀土氯化盐水溶液随浓度的增加,电导率逐渐升高,摩尔电导率逐渐减小.

关键词: 稀土氯化盐水溶液, 电导率, 摩尔电导率

Abstract: The electric conductivity of rare earths salt ErCl3,DyCl3,NdCl3 and YCl3 was determined in H2O at 298 K by conductivity meter,and the molar conductivity was calculated according to the related formula.The effect of concentration on the electric conductivity and molar conductivity was discussed.With the  increasing concentration of rare earths salt  solution,the conductivity proportion of rare earths salt in the solution got higher and the molar conductivity of rare earths salt got lower.

Key words: rare earths salt , solution;conductivity proportion;molar conductivity
