Conductance Behaviour of Silver [Cryptand 2,2,2] Perchlorate Complex in Water-Acetonitrile and Methanol-Acetonitrile Mixtures

Conductance studies on silver [Cryptand 2,2,2] perchlorate complex have been made in water-acetonitrile and methanol-acetonitrile mixtures over the complete range of solvent compositions at 30 °C. The data were analysed by the Fuoss 1980 three parameter equation and the variation of the Walden products of respective ions with solvent composition was analysed. The considerable decrease of the Walden products of {silver [Cryptand 2,2,2]} + has been explained in terms of the selective solvation of the ion by acetonitrile in both solvent mixtures.
