Abstract

Electrical conductivities of dilute aqueous solutions for unsymmetrical electrolytes of the type 3:1, 1:3, 3:2, 4:1, 1:4, 4:2, 2:4, 1:5 1:6 and 6:1 are reexamined in the framework of the Quint-Viallard conductivity equations, in order to obtain a uniform representation of their conductivities. The molar and equivalent limiting conductances were evaluated with ion association constants, which were treated as adjustable parameters. The derived values were compared with corresponding results from the literature. The following electrolytes are considered: rare earth (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er) halides, perchlorides, nitrates and sulfates; hexamminecobalt and tris- ethylenediaminecobalt halides, perchlorides, nitrates and sulfates; [Ni 3(trien)3]Cl4, [Pt(pn)3]Cl 4, [Co2 (trien)3]Cl6; cyanides K3[Fe(CN)6], K3[Co(CN)6], M 3[W(CN)8] with M = Na, K, Rb, Cs; Ca2[Fe(CN) 6], K4[Fe(CN)6], K4[Mo(CN) 8], K4[W(CN)8], K4[Ru(CN) 8], (Me4N)4]Fe(CN)6], (Pr 4N)4]Fe(CN)6], K4[Mo(CN) 8], (Me4N)4]Mo(CN)8], (Et 4N)4]Mo(CN)8] and (Pr4 N) 4]Mo(CN)8]; phosphates Na4P2O 7, Na4 P4O12, Na5 P 3O10, Na6P6O18 and (Me4N)4P4O12.
