چكيده فارسي :
In this research, the ionic conductivity of 1-Butyl-3-methyl imidazolium Bromide in water and DMA mixtures was measured in different mass fractions of DMA mixtures((w/w)% = wDMA / wmixture =0, 10 and 20%) at T = (298.2, 308.2) K. The conductivities data were analyzed by Fuoss Onsager equation. The ion association constant (KA), limiting molar conductivitiy (Λ0) was obtained through correlation of experimental data. The obtained parameters were used to calculate the standard Gibbs free energy of aggregation.
