Abstract:
Abstract Attempts have been made to prepare some novel copper(I) nitrate, sulfate, and perchlorate complexes. Molar conductances of these complexes have been measured in organic solvents like acetonitrile (AN), acetone (AC), methanol (MeOH), N,N-dimethylformamide (DMF), N,Ndimethylacetamide (DMA), and dimethylsulfoxide (DMSO) at 298 K. The molar conductance data have been analyzed to obtain limiting molar conductances (λ0) and ion association constants (KA) of the electrolytes. The results showed that all these complexes are strong electrolytes in all organic solvents. The limiting ionic molar

Abstract:
Conductance, potentiometric, and spectrophotometric measurements have been made at 25°C of aqueous solution containing sulfanilic, hippuric, mandelic, and 3,5-dinitrosalicylic acids at different concentrations. Conductance data were analyzed using the methods of Fuoss-Kraus, Kraus-Parker, and Shedlovsky for conductivity of the free ions. Using the calculated limiting conductances, activity coefficients, and degrees of dissociation, the dissociation constants of the weak acids were determined. From plots Δ vs c1/2, reliable values for Δ0 were estimated, using a computer program, and by means of

State of the art conductivity equipment has been used to measure deuterium isotope effects on the molar conductivity of strong electrolytes in the temperature range of 298 K to 598 K as a means of exploring solvation effects under hydrothermal conditions. Individual ionic contributions were determined by extrapolation of published transference number data to elevated temperature. The temperature dependence of the Walden product ratio indicates that there is little difference in the transport of ions between light and heavy water .
