Abstract

New estimates of ionic viscousity B-coefficient and NMR B′-coefficient have been obtained in aqueous solutions over the temperature range 0 to 95 °C by a recently developed method. The derived values for the alkali metal and halide ions have been compared with the existing ones and the discrepancies discussed. Temperature effect on the two coefficients for the simple inorganic ions has been satisfactorily discussed using the concept of the Frank and Wen model. Energy of activation for viscous flow has also been calculated using the Eyring model and three different values are obtained for each ion over the temperature range studied.
