| Abstract: | The electric conductivity of rare earths salt ErCl_3,DyCl_3,NdCl_3 and YCl_3 was determined in H_2O 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. |
| |
| Keywords: | rare earths salt solution conductivity proportion molar conductivity |
