| Abstract: | Ultrasonic velocities in dilute solutions of water in n-propanol, isopropanol, glycerol, formamide. N-methyl formamide, dimethyl formamide tetrahydrofuran and propylene glycol have been determined 298.15 K using single crystal variable path interferometer working at 3 Mhz. Excess sound velocities, have been evaluated using the formula which is thermodynamically valid. Both the ultrasonic velocity and excess ultralsonic velocity have been found to vary nonlinearly with concentration in the high dilution range of water in non electrolytes studied. The results are explained by considering the existence of water molecules as monomer up to certain optimum concentration (X2)opt of water and the nonlinear behaviour observed beyond (X2)opt has been explained in the light water-water and water- nonelectrolyte interactions leading to the formation of island of water-nonelectrolyte complexes. |
