Data 2006 2006-10-06 Compressibility Studies of Binary Solutions Involving Water as a Solute in Nonaqueous Solvents at T ) 298.15 K The experimental measurements of the speed of sound and density in binary solutions of MeOH, EtOH, n-PrOH, n-BuOH, acetonitrile (ACN), dimethylformamide (DMF), tetrahydrofuran (THF), and 1,4-dioxane as solvents and water as the solute in the concentration range of 0.02 molakg-1 to 1 molakg-1 at T ) 298.15 K are reported. The data are used to obtain the isentropic compressibility of solution. The apparent molar volume ( V) and compressibility ( K) of water at different concentrations are evaluated. The data of limiting volume ( V 0 ) and compressibility ( K 0 ) and their concentration variation are examined to study the effect due to water-solvent and water-water interactions. It has been observed that there is loss of volume and compressibility of liquid water molecules in transferring them from the pure liquid state to a nonaqueous solvent. An attempt is made to explain the large negative value of K 0 in alcohols due to H-bonding characteristics of water and alcohol and the effect of the presence of nonpolar groups. The possibilities of the presence of water-centered complexes or participation of water in a chain-like structure along with pressure effects are examined on the basis of concentration variation of the derived properties. 51 1617-1623 1 methanol CH4O 1 Commercial source 1 .0469 3 Karl Fischer titration 2 ethanol C2H6O 1 Commercial source 1 .1201 4 Karl Fischer titration 3 1-propanol C3H8O 1
