A STUDY OF SOME PHYSICAL PROPERTIES FOR B12 IN AQUEOUS SOLUTION AT FOUR TEMPERATURES

Abstract

Solute- solvent interaction was investigated in this study using the vitamin B12 as solutes in water as a solvent at four different temperatures.The densities and viscosities of solutions of B12 in water at 293.15, 298.15, 303.15 and 308.15 K have been measured. The study covered calculations partial molal volume from densities measurements; 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
