Abstract : The density (ρ), viscosity (η) and ultrasonic velocity (U) of aqueous solution of ascorbic acid (vitamin C) at temperature 293K and 303K have been measured. Using this experimental data , other thermo-acoustical parameters such as adiabatic compressibility (β),relaxation time (τ), classical absorption (α/f2), free volume (Vf), internal pressure (Pi), have been calculated and studied. These parameters have been used to give the interpretations of solute solvent interaction of water and ascorbic acid molecules. Furthermore these studies shows that the nature of molecular interaction in aqueous solution of ascorbic acid (vitamin C) and it provide important information regarding molecular properties of solute and solvent interaction. The obtained result show significant influence of concentration and temperature on the molecular aggregation, which is helpful in pharmaceutical and food industries to prepare various drug dosages, tablets, syrups, capsule, soft gel and injection in liquid form.
