Tóm tắt

The molar conductivities of silver nitrate and perchlorate solutions in aqueous ethanol (X EtOH = 0.5–0.9 and X EtOH = 0.9, respectively) were measured. Using the conductometry data, the values of dissociation constants and limiting conductivities (λ 0) of these electrolytes were calculated. The results were discussed by employing a solvation-thermodynamic approach. The hydrodynamic radii of Ag+, $$ {\text{NO}}_{3}^{ - } $$ and $$ {\text{ClO}}_{4}^{ - } $$ ions were estimated.
