摘要
测定了ＮａＣｌ－ＲｂＣｌ－Ｈ２Ｏ及ＫＣｌ－ＲｂＣｌ－Ｈ２Ｏ两种混合电解质体系在不同离子强度配比下的电导数据。应用现代Ｏｎｓａｇｅｒ－Ｆｕｏｓｓ－Ｃｈｅｎ理论，以经验线性项代替理论中的高次项，得到关联方程。研究了混合电解质溶液的混合效应，发现不同配比下均呈负效应，但效应不明显。
The conductivity of dilute aqueous solutions of NaCl-RbCl,KCl-RbCl has been determined at various ionic strength rations. The higher order term has been replaced by an empirical linear one in Onsager-Fuoss-Chen theory of conductance for mixtures, and the simplified theory has been applied to correlate the experimental data. The mixing effect has been investigated,and found to be approximately ideal on equivalent conductance.
