盐酸在H_2O与DMSO-H_2O间的迁移热力学函数

THE TRANSFER THHERMODYNAMIC FUNCTIONS of HCl from H_2O to DMSO-H_2O

用电动势法测定了盐酸在水与二甲亚砜一水混合溶剂中的电动势,计算出了298.15K下的迁移自由能、迁移及迁移熵,据此对溶液的微观结构作了定性讨论.并采用Abraham的离子溶剂化一层连续介质模型对△G_t^O进行了理论计算,结果表明计算值与实验值基本符合.

This Paper measured the Emfs of HC1 in H_2O and DMSO-H_2O by the EMF method. According to the experimental data of E_m^o, the thermodynamic functions AG_t^o、△H_t^(o)and △ S_t^o have been calculated. Based on these transfer function data, the micro-structure o solution have been discussed, Furthermore, we also caculated the transfer free energy △G_t^o of HC1 theoretically using Abrham single coat continuous model. The results show that the caculated value is identical with the exprimental value.
