Abstract :
Solute-solvent interaction was investigated in this study using the vitamins Bi and B3 as solutes in water as a solvent at four different temperatures. The study covered theoretical calculations concerning partial molal volume, Van der Waals volume and some related parameters as well as experimental measurements; a comparison and discussion was made, viscosity measurements have been performed for the above system. The applicability of Jones-dole equation has been discussed in terms of concentration and temperature effects and then related to the results of partial molal volume.
