The densities of the binary solvent mixtures and their salt solutions have been measured by one of the recently modified techniques, namely the Magnetic Float Densitometer. The partial molar volume or apparent molar volume φv at infinite dilute are determined by φ_v^0 values of solution mixtures for tetra butyl ammonium iodide salt from aqueous to non-aqueous solvent mixture of the Water-Ethanol system. The φv values showed large and positive values, due to weak ion-ion interactions between the components of mixtures. It increases by decreasing the concentration of ethanol. However, the value of slope Sv showed a negative value for Bu4NI salt solutions. This is due to the presence of specific molecular interactions that will lead to an increase in electrostriction with the presence of water in the solution mixture.
