Özet

The thermodynamic functions for the formation of benzoate complexes of cobalt(II), nickel(II) and manganese(II) have been determined by measuring the pertinent stability constants potentiometrically at temperatures within the range 25-40-degrees-C. From the enthalpy changes evaluated, and the free energy changes calculated from the stability constants, the entropy changes were found. All data refer to a sodium perchlorate medium of ionic strength 1.0 M.
