Conductivity and Mixing Effect of Dilute Solutions of Mixed Electrolytes-Systems NaCl-RbCl-H₂O and KCl-RbCl-H₂O at 298.15K

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 The higher order term has been replaced by an empirical linear one in Onsager-Fuoss-Chen theory of conductance for mixtures, and the simplified theory has been applied to correlate the experimental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.
