Ultrasonic Investigation as a Tool for Assessing Behaviour of Multicomponent Systems
Ultrasonics has been a powerful tool for studying structural and physico-chemical properties of liquids, liquid mixtures and electrolytic solutions. Ultrasonic speed measurements are helpful for interpreting solute-solute, solute-solvent interactions in aqueous and co-aqueous medium in terms of derived parameters viz. Apparent molal Compressibility, Acoustic Impedance, Intermolecular Free Length etc. Bio-molecules play a vital role in the various biochemical processes occuring in living organisms. Their interactions studies throw a light on the structural complexity of these bio-molecules, which cannot be assessed directly. The present study provides new information from chemical and biological point of view to understand the interactions of threonine and dl-alanine in aqueous or co-aqueous DMF and uracil in the presence of Na2SO4 in aqueous urea solution.
Keywords
