在恒定溶液总离子强度Ｉ＝１．００ｍｏｌ·ｋｇ－１，改变特丁醇在混合溶剂中的质量百分数ｘ＝５％、１５％和２０％的条件下，测定了无液接电池（Ａ）和电池（Ｂ）的电动势，确定了混合溶剂中的Ａｇ－ＡｇＣｌ电极的标准电极电势，讨论了ＨＣｌ的迁移性质；计算了ＨＣｌ在该体系中的活度系数γＡ，结果表明，对于所讨论的体系，在溶液中总离子强度保持恒定，ＨＣｌ的活度系数服从Ｈａｒｎｅｄ规则．在溶液组成恒定时，ｌｇγＡ是温度倒数１／Ｔ的线性函数，计算了ＨＣｌ一级，二级和总介质效应
(A) was measured under the conditions of a constant total ionic strength I = 1.00mol · kg-1, the mass percentage of tetrabutyl alcohol in the mixed solvent x = 5%, 15% and 20% And the electromotive force of the battery (B), the standard electrode potential of the Ag-AgCl electrode in the mixed solvent was determined, the migration property of HCl was discussed, and the activity coefficient of HCl in the system was calculated. The results show that for the discussed System, the total ionic strength in the solution remains constant, and the activity coefficient of HCl obeys the Harned rule. When the composition of the solution is constant, lgγA is a linear function of the reciprocal of the temperature 1 / T and the primary, secondary, and total medium effects of HCl are calculated
