The ultrasonic study can give the information of complex formation through hydrogen bonding in the system. Ultrasonic is an area of intense scientific and technological research. Ultrasonic parameters provide valuable information about various inter and intra interaction in solutions. Dichlofenac Sodium is an analgesic and used in pharmaceuticals. Ultrasonic velocity, density and viscosity were reported for aqueous solution of Dichlofenac Sodium at different temperatures. The ultrasonic velocity and its derived parameters were employed to investigate solute-solvent interaction.
