Hazra] Precise measurements on electrical conductances of the solutions of lithium chloride (LiCl), lithium bromide (LiBr), lithium iodide (LiI), lithium perchlorate (LiClO4), lithium tetrafluoroborate (LiBF4), sodium bromide (NaBr), sodium tetraphenylborate (NaBPh4), potassium bromide (KBr), rubidium bromide (RbBr), cesium bromide (CsBr) and tetrabutylammonium bromide (Bu4NBr) in N,N-dimethylacetamide+water (50 v/v) mixture have been reported at 25°C in the concentration range 0.02-0.05moldm−3. The conductance data have been analyzed by the 1978 Fuoss conductance-concentration equation in terms of the limiting molar conductance (Λ0), the association constant (KA) and the association diameter (R). The limiting ionic conductances (λ0±) have been estimated from the appropriate division of the limiting molar conductivity value of the "reference electrolyte” tetrabutylammonium tetraphenylborate (Bu4NBPh4). The electrolytes investigated here are found to be significantly dissociated in this solvent medium and all ions remain unsolvated in N,N-dimethylacetamide+water (50 v/v) mixed solvent system with exception of the lithium ion where significant solvation has been noticed. The results have been interpreted in terms of the specific constitutional and structural factors of the solvent and of the solute ions. © 2004 Oldenbourg Wissenschaftsverlag GmbH Thermodynamics & statistical physics nationallicence Laboratory techniques, experiments nationallicence Physical chemistry nationallicence Das Debashis aut Das Bijan aut Hazra Dilip K. aut Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/3/2004(2004-03-01), 341-348 0942-9352 218:3/2004<341 2004 218 zpch https://doi.org/10.1524/zpch.218.3.341.26490 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/zpch.218.3.341.26490 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Das Debashis aut NATIONALLICENCE 700 1- Das Bijan aut NATIONALLICENCE 700 1- Hazra Dilip K. aut NATIONALLICENCE 773 0- Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/3/2004(2004-03-01), 341-348 0942-9352 218:3/2004<341 2004 218 zpch CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
