摘　　要：改变乙醇在混合溶剂中质量分数(x=0%,5%,15%)的条件下,测定了无液接电池(A)和电池(B)的电动势,确定了AgCl-Ag电极和Zn电极及其电极对在溶液中的标准电动势,计算ZnCl2在混合电解质溶液中的热力学迁移性质和平均活度系数r±.The potential of cell A and cell B was determined on condition that the weight percentage of Alcohol in mixed solvent was 5%, 10% and 15% respectively.The standand electrode potentials of Ag-AgCl,Zn and the electrode pair in solvent were defined,the termodynamic property and the average activity coefficient of zine cholride in mixed solvent were counted.

关 键 词：混合溶剂溶液 热力学迁移性质 平均活度系数 电动势法
