    Sedimentation potential of complexes of nitroamminecobalt(III) in aqueous solution at 25°C (1990)
    Springer
    Journal of solution chemistry 19 (1990), S. 11-17

    ISSN: 1572-8927
    Keywords: Sedimentation potential ; partial molar volume ; ionic partial molar volume ; nitroamminecobalt(III) complexes

    Topics: Chemistry and Pharmacology
    Notes: Abstract Sedimentation potentials (SP) were measured for a series of nitroamminecobalt(III) chlorides in aqueous solution. The magnitudes of the sedimentation potentials varied with the number of NO 2 − ligands in the complexes and a definite positive signal was observed for a neutral complex [Co(NO2)3(NH3)3]0. The division of the partial molar volumes of nitroamminecobalt(III) complexes based on the observed SP values resulted in comparable values of the partial molar volume for the Cl− ion, suggesting no appreciable hydrolysis nor ionic association occur for these nitroammine-cobalt(III) complexes.

    Dissolved states of ionene polymers in water-acetone and their relation to the ionic partial molar adiabatic compressibility and volume (1991)
    Springer
    Journal of solution chemistry 20 (1991), S. 1129-1138 
    Details
    ISSN: 1572-8927
    Keywords: Ionene polymer ; partial molar volume ; partial molar adiabatic compressibility ; ion-binding ; water-acetone system
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Solution properties of water-soluble synthetic polymer, 3,3-ionene and 6,6-ionene chloride and bromide disolved in water-acetone mixtures up to acetone content 50 wt% were investigated. Their partial molar volumes V 2 o and partial molar adiabatic compressibilities K s o were determined. Ionic additivity of V 2 o with respect to the cation of backbone polymer chain and the counter-anion was confirmed quantitatively. The ionic additivity of V 2 o is discussed along with the K s o in their relation to the counterion binding of ionene polymers. Effects of ionic sites on the ionene are strong but they don't break the solvation layer.
