VISCOSITY AND ACOUSTIC BEHAVIOR OF CARBONATO PENTAMINE COBALT(III) NITRATE IN WATER AND GLYCEROL-WATER MIXED-SOLVENT SYSTEM

The ultrasonic velocity and viscosity of carbonato pentamine Co (III) nitrate in water and different proportions of glycerol-water mixtures were determined at 303.15 K. The Jones-Dole viscosity B-coefficient of the coordination complex is found to be largest in 40% (v/v) glycerol -water mixture. Various acoustic parameters viz isentropic compressibi lity, intermolecular freelength, acoustic impedance, etc. have been ca lculated using experimentally determined values of ultrasonic velocity and density. The variation of these acoustic parameters are discussed in the light of solute-solvent and solute-solute interactions. (C) 19 97 Elsevier Science B.V.
