COMPARATIVE STUDY OF SPECIFIC ACOUSTIC IMPEDANCE AND TRANSPORT PROPERTIES OF SULFA COMPOUNDS USING ULTRASONIC VELOCITY
AbstractMeasurement of ultrasonic velocity in non-aqueous solution gives information about the behavior of solution such as molecular association and disassociation. The attraction and repulsion between the molecules of the components involved show considerable effect upon the physical and chemical properties of a solution such as density, viscosity, and ultrasonic velocity. The ultrasonic velocity data combined with density and viscosity provides the standard means for determining the acoustical parameters and internal pressure, free volume. The Specific acoustic impendence in solutions can be used as a tool to estimate the strength of intermolecular attraction. Internal pressure (πi) and free volume (Vf) are the transport properties, which are useful in understanding the intra and intermolecular interactions. Internal pressure gives an idea of the solubility characteristics. Sulphanilamide is a parent compound and also the potent antibiotic which is important in urinary tract infections and meningococcal meningitis profilaxes 1. Another sample Sulphadiazine is the Sulphonamide potent antibiotic, and it is a competitive inhibitor of the bacterial enzyme dihydropteroate synthesis.
