*Dr. Kapadnis K.H.

ABSTRACT

The volumetric and viscometric studies of glucose and fructose have been determined in 0.05M and 0.5M KBr and NaCl solutions at 298.15and 313.15K.The apparent molar volume (v) values vary linearly with square root of concentration of KBr and NaCl solution. The limiting apparent molar volume (0v) has been interpreted in terms of solute-solvent interaction. The 0v values vary with temperature and can be represented in the power series of structure modifying capacity of electrolyte KBr and NaCl is inferred from the sign of dB/dT values. The apparent molar expansibility has also been determined Sugars have been found to be structure-maker/breaker in aqueous KBr and NaCl from molar volume i.e. Density as well as viscosity studies.
