摘要
应用电导法测定了 2 98K时稀土氯化盐 La Cl3 在水中的活度系数 ,在 2 98K时测定了La Cl3 在水中的电导率 ,利用公式计算了 La Cl3 的摩尔电导率 ,应用 Debye- Hücker和 Osager-Falkenhangen公式计算了 La Cl3 在水中的活度系数 ,并讨论了在 2 98K时浓度对 La Cl3 水溶液活度系数的影响 ,随 La Cl3 溶液浓度的增加 ,La Cl3 水溶液的活度系数降低。
In this paper, we applied in activity coefficient of Rare Earths salt LaCl_3 in H_2O at 298K with conductivity method , Determined electrice conductivity of Rare Earths salt LaCl_3 in H_2O at 298K , The use of formula has calculated the molar conductivity of Rare Earths salt LaCl_3 in H_2O at 298K, The use of Debye-Hücker and Osager-Falkenhangen formula has calculated the activity coefficient of Rare Earths salt LaCl_3 in H_2O at 298K , and discussed the effect of concentration on activity coefficient of LaCl_3 electrolyte solution at 298K. With the inereasing of the concentration of Rare Earths salt LaCl_3 in water, the activity coefficient of Rare Earths salt LaCl_3 in water got lower.
