Abstract
The effect of composition of ethanol–dimethyl sulfoxide (EtOH–DMSO) solvents (χDMSO = 0.0–1.0 mole fractions) on the stability of silver(I) complexes with 18-crown-6 ether (18C6) has been studied potentiometrically at 298.15 K. The increasing of DMSO concentrations in mixed solvents are shown to considerably reduce the stability of 18C6 complexes with silver(I) ion ([Ag18C6]+). A change in the solvation state of the central ion is suggested to be the key factor in shifting complexing equilibrium.
