VISCOSITY AND ULTRASONIC STUDIES OF CARBONATO-BIS (ETHYLENE DIAMINE) COBALT(III) PERCHLORATE IN WATER AND GLYCEROL-WATER MIXED-SOLVENT SYSTEMS

The ultrasonic velocity, density and viscosity of carbonato-bis(ethyle ne diamine) cobalt(III) perchlorate solution in water and 10%, 20%, 30 %, 40% glycerol-water mixtures have been measured at 303.15K. Various acoustic parameters such as isentropic compressibility, free length, a coustic impedance have been obtained from the experimental data for al l the solutions. The nature of variation of these acoustic parameters give information about the type of interaction taking place in these s ystems. The co-ordination complex behaves as a structure breaker in gl ycerol-water mixed solvents.
