Abstract: The electrical conductance of nicoitinium dichromate has been measured in water-N,Ndimethyl formamide mixtures of different compositions in the temperature range 283-313 K. The limiting molar conductance, o and the association constant of the ion-pair, KA have been calculated using Shedlovsky equation. The effective ionic radii (ri) of (C6H6O2) + and (C6H6O2NCr2O7)-ions have been determined from i o values using Gill's modification of the Stokes law. The influence of the mixed solvent composition on the solv… Show more

“…The limiting molar conductance values (Λ o ) and the association constants (log K ass ) for the nickel(II) and cobalt(II) complexes were computed using Shedlovsky’s [ 25 ] and Pitt’s [ 26 , 27 ] equations and are consequently collected in Table 4 .…”

“…The titrant (5 mM [Co(ODA)(H 2 O)] or [Ni(ODA)(H 2 O) 3 ]) was added to the titrand (0–50 % v/v DMSO-H 2 O) both at the same mole fraction of organic solvent, in increments of 0.01 mL, with a pause of 60 s. Each titration was repeated at least three times in order to check the reproducibility of the data. The limiting molar conductance values (Λ o ) and the association constants (log K ass ) for the nickel(II) and cobalt(II) complexes were computed using the Shedlovsky’s [ 25 ] and Pitt’s [ 26 , 27 ] method. The physicochemical parameters of the binary solvents used in the calculations were taken from the literature [ 28 33 ].…”

“…The influence of various temperatures on conductivity measurement can give detailed information of ion-ion and ion-solvent interaction for different electrolytes solution [18][19][20][21][22][23][24][25][26][27][28][29][30]. Molecular associations in liquid system and their variations with composition and temperature were studied by thermodynamic data [31][32][33][34][35][36][37][38]. Transition metals occupy the space between group II and group III of the periodic table and due to their unique physical and chemical properties are of great interest.…”
