Abstract
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.Keywords
