Viscosities of four new types of polycationic electrolytes possessing N-alkyl/Nacylammonium and 2,5-thiophenylene linkages in their respective repeating units of the chain (Mol. Wt. 1154-3815) have been studied in the two dipolar aprotic solvents viz., dimethylformamide (DMF) and dimethylsulfoxide (
Transition-state treatment has been used for calculation of the contributions per mole of the solute. to the free energy of activation for viscous flow of lithium chloride, lithium nitrate and lithium, sodium and potasium perchlorates solutions in dimethylformamide-water mixtures. The values obtaine
Equivalent conducfances of Bu4NN03, AgNO. and Kl in methanol (MeOH) and those of Bu4NBPh4, Bu+NNOs, ByNI, AgNOs and KI in several N,N-dimethylformamide+methanol (DMF + MeOH) mixtures over the entire solvent composition range have been measured at 25Β°C. The conductance data in ail the case-s have bee
