Abstract: Studies of apparent molar volume have been made in the solutions of trans- bis (1,2-diaminoethane) (amino-carboxylato) halogeno cobalt (III) complexes containing the carboxylato-bonded aminoacids, e.g. glycine, α-alanine and β-alanine in water, water+acetone (5,10 & 20 wt %) and water+alcohol (5 wt % each of methanol, ethanol and n-propanol) mixtures at 298.15, 303.15, 308.15 and 313.15 K to evaluate apparent molar properties. Studies of ultrasonic velocity have also been made for the solutions of these complexes in these solvents at 303.15, 308.15 and 313.15 K to evaluate various acoustic parameters. The results are discussed in the light of ion-ion and ion-solvent interactions and of structural effects of the solvent in solutions.
