Ionic association and conductances of sodium perchlorate in N,N-dimethylformamide + water and tetrahydrofuran + water at 298 K

Conductometric study on sodium perchlorate and sodium benzoate in binary mixtures of 1-propanol + water at 298.15 K

“…The decrease in Aq values may be attributed to increasing viscosities of 1-propanol + water mixtures (Table 1) and different solvation of the ions. Similar results were not found in previous studies (4,5). The difference may be attributed to different solvent systems.…”

“…In two previous papers (4,5), the association behavior of these salts was reported in aqueous mixtures of acetonitrile, N^V-dimethylformamide, and tetrahydrofuran. The present paper reports molar electrolytic conductivities of these salts in mixtures of water with up to 41 mol % 1-propanol.…”

Conductivities, Partial Molar Volumes, and Isentropic Compressibilities of Sodium, Potassium and Ammonium Thiocyanates in Water + N,N-Dimethylformamide Mixtures at 20°C

“…Conductance and density measurements of alkali-metal halides and alkalimetal perchlorates in pure DMF [1,2] and binary mixtures containing DMF [3][4][5] are now plentiful in the literature, but such studies for alkali-metal thiocyanates are lacking. In the literature appear reports of conductivity studies for NaSCN and KSCN in 1-propanol and 2-propanol [6,7].…”

Ionic Association and Conductances of Some Symmetrical Tetraalkylammonium Perchlorates in 2-Methoxyethanol + Water at 298.15 K

“…Extensive studies on the electrolytic conductivities in the binary mixtures of water with various organic solvents have been made in recent years (Niazi et al, 1993;Roy et al, 1993;Papadopoulos and Ritzoulis, 1989;Das and Hazra, 1988;Bahadur and Ramanamurti, 1984;Raju et al, 1982) to examine the magnitude and the nature of ionion and ion-solvent interactions. The solvent properties such as the viscosity and the dielectric constant have also been taken into account in determining the extent of ion association and the solute-solvent interactions.…”
