Abstract
The concept of Frank’s hypothesis (that is the effect of large tetra alkyl ammonium iodides on the solvent structure, especially in the ion – ion and ion – solvent interactions) was found to be not applicable when water was replaced by one of organic solvent. That is, if study involves ion- ion and ion – solvent interactions in 1, 3 – Butane diol – DMF solvent mixture. The densities of these mixture and some adding tetra alkyl ammonium iodide salts solutions at different concentrations (0.02 – 0.14 M) have been determined at 298.15 K using Magnetic Float Densitometer technique. The apparent molar volume (ϕv) and apparent molar volumes of transfer ∆ϕv0 (tr) of the electrolytes in above solvent mixtures were calculated. ϕv vs √C curves are plotted and explained the nature of molecular interactions by using slope (Sv) values. Also, the significant role of varying dielectric constants (ϵ) of the selected solvent mixtures in the ionic interaction is discussed.
