摘　　要：用电动势法测定了五个温度下总离子强度I恒定为0.2,0.4,0.6,0.8,1.0mol·Kg-1时CuCl2在乙醇——水混合溶剂中的平均活度系数,实验结果表明,在温度10℃,15℃,20℃,25℃和30℃时,CuCl2的活度系数能较好地符合Harned规则.The activity coefficient of CuCl2 within CuCl2-C2H5OH-H2O system are tested with the EMF under five temperature ranges and grossionic strength I identifyied with 0.2,0.4,0.6,0.8,1.0 mol·kg^-1 respectively. The result of the experiments shows that the activity coefficient of CuCl2 is in accord with Harned rule at temperature 10℃,15℃,20℃,25℃ and 30℃ respecively.
