Viscosities and molar conductances of Bu4NBPh4, Bu4NClO4, CuClO4*4AN, AgClO4 and TlClO4 have been measured in the concentration ranges (30-425)E-4 mol dm-3 and (1-35)E-4 mol dm-3, respectively in acetonitrile-pyridine (AN-Py) mixtures containing 0, 10, 20, 40, 60, 80, 90 and 100 molpercent AN at 15, 25 and 35 deg C.The viscosity data have been analysed using the Jones-Dole equation in the form: η/η deg = 1 + AC1/2 + BC for unassociated electrolytes and in the form: η/η deg = 1 + A(Cα)1/2 + BCα + B'(1-α)C for the associated electrolytes.The A-coefficients of the Jones-Dole equation are positive and in reasonably good agreement with the limiting theoretical values (Aη) calculated at all the three temperatures using Falkenhagen-Vernon equation.The B-coefficients of the electrolytes are also positive and large in all cases and show a significant decrease with increase in temperature.The ionic B+ and B- coefficients have been evaluated from the B-coefficients of the electrolytes using a method reported by Gill and Sharma.The derived viscosity results show preferential solvation of Cu+, Ag+ and Tl+ by Py in AN-Py mixtures at all the temperatures studied.
