Abstract: Density and Ultrasonic velocity Sucrose in 1M NaCl at 298.15K, 303.15K, 308.15K and 313.15K have been measured. Various ultrasonic and solution parameters such as adiabatic compressibility, change and relative change in adiabatic compressibility, acoustic impedance, available volume and free length have been calculated using these data. The present investigation has been used to exploit the possible molecular interactions which are identified and eventually discussed about the behavior of solute (Sucrose) in the solvent 1 M solution of NaCl)
