Abstract:

Viscosities and densities at 298.15 and 308.15K are reported for NaCl and KCl in aqueous sucrose solutions. The viscosity B coefficients and partial molar volumes at infinite dilution have been calculated. The experimental results show that B coefficients increase with the increase of sucrose concentration and of temperature and that the two electrolytes are structure-breakers for the sucrose aqueous solutions. The terms of solute-solute and solute-solvent interactions in ternary water-sucrose-electrolyte systems are discussed. Also the activation parameters for viscous flow of NaCl and KCl in this system have been calculated.

Key words: Viscosity B coefficient, Activation parameter, Interaction, Partial molar volume
