The acidity constants of the ω-aminosulphonates NH2(CH2)SO3− with n = 2, 3,4 and 5 and the stability constants of the Ag(I) complexes of these ligands were determined at 25°, in 0.5 M KNO3. The enthalpy- and entropy changes accompanying the formation of the Ag(I) complexes of the same ω-aminosulphonates and the corresponding ω′-aminoalkylpyridinium compounds were calculated from calorimetric data. The influence of a negative and of a positive substituent on these thermodynamic functions is briefly discussed. |
