【 摘 要 】

Density (ρ), apparent molar volume (ϕoV) and viscosity (ɳ) of ammonium sulphate at different temperatures (303.15 and 313.15 k) are reported for binary mixtures of N,N-dimethylformamide (DMF) and water over entire range of mole fractions. The apparent molar volume, limiting apparent molar volume, Jones dole A and B coefficient were calculated. The study of structural interactions by means of molar volume has received vital importance in physical chemistry. The apparent and partial molar volume of electrolytic solutions have proven to be very useful tool in elucidating the solute-solute, solute-solvent and solvent-solvent interactions occurring in solution. The related parameters correlated to the present study such as limiting apparent molar volume (ϕoV) and their associated constant (Sv) and viscosity B coefficient of Jone – Dole equation. The results show strong solute-solvent interactions at 303.15 and 313.15 k temperature.
