10.22376/ijpbs.2019.10.1.p1-12 Volume 4 Issue 3 2013 (July - September) The ultrasonic velocity ( lessThan i greaterThan U lessThan /i greaterThan ) of potassium ferricyanide and ferrocyanide has been measured at 298.15 K only. The density (d) and viscosity ( lessThan i greaterThan η lessThan /i greaterThan ) of both the electrolytes have been measured in the concentration range of 1×10 lessThan sup greaterThan -2 lessThan /sup greaterThan to 1×10 lessThan sup greaterThan -1 lessThan /sup greaterThan mol dm lessThan sup greaterThan -3 lessThan /sup greaterThan in aqueous binary mixtures containing dextrose (5, 10, 15% (w/w)) at different temperatures ranging from 298.15 to 313.15K. Various important parameters, such as apparent molar volume ( lessThan i greaterThan V lessThan sub greaterThan Φ lessThan /sub greaterThan lessThan /i greaterThan ), limiting apparent molar volume ( lessThan i greaterThan V lessThan sub greaterThan Φ lessThan /sub greaterThan lessThan sup greaterThan 0 lessThan /sup greaterThan lessThan /i greaterThan ), apparent molar expansibility ( lessThan i greaterThan E lessThan sub greaterThan Φ lessThan /sub greaterThan lessThan /i greaterThan ), isentropic compressibility ( lessThan i greaterThan K lessThan sub greaterThan s lessThan /sub greaterThan lessThan /i greaterThan ), solvation number ( lessThan i greaterThan S lessThan sub greaterThan n lessThan /sub greaterThan lessThan /i greaterThan ) and other viscosity parameters have been computed using experimentally determined values of ultrasonic velocity, density and viscosity. In the light of solute-solvent and solute-solute interactions, the variation of these parameters has been enlightened. The viscosity data have been analyzed on the basis of Jones-Dole equation to know the molecular interactions. SUJIT KUMAR DEHURY, MALABIKA TALUKDAR AND UPENDRA NATH DASH.
