Ion association and solvation of silver monocarboxylates in water + mannitol and water + sorbitol mixtures at different temperatures: A conductivity study

Abstract

The conductivities of silver acetate, silver propionate and silver benzoate have been measured in water + 5 wt% mannitol and water + 5 wt% sorbitol at 20, 25, 30 and 35°C, and analysed using Fuoss-Hsia equation in the form of Fernandez-Prini coefficients and Shedlovsky and Fuoss-Kraus extrapolation techniques for calculating the association parameters (Λ₀ and <i>K</i>_A). A comparison of these parameters revealed that the Shedlovsky method is superior to other methods and predicted better association constants for the silver monocarboxylates in these aqueous isomeric solvents.
