| 摘 要： | 用电导法测定了醋酸在不同温度时和不同浓度下在H2O和THF混合溶剂中的电导丰，应用Debye-Hucker和OsagerFalkenhangen公式计算了醋酸在混合溶剂中的活度系数。并讨论了温度和浓度对电解质活度系数的影响。结果表明。电解质溶液的活度系数随着温度的增加而增大，随着浓度的增加而减小。

| Abstract: | The electric conductivity of CH3OOH with different concentration in mixed solvent of H2O and THF at temperature ranging from 292K to 312K is measured with conductivity method. The activity coefficient of CH3OOH in H2O and THF is calculated by using DebyeHucker and Osager-Falkenhngen formula. In addition, the effects of concentration and temperature on activity coefficient ate discussed. The results show that when temperature increases, the activity coefficient will increase;when concentration increases, the activity coefficient will decrease. |
