Activity coefficients of NaCl in the NaCl + NaBF4 + H2O ternary system at 298.15 K
چکیده انگلیسی

The activity coefficients of sodium chloride in the NaCl + NaBF4 + H2O ternary system were experimentally determined at 298.15 K, at ionic strengths of 0.3. 0.5, 1, 2 and 3 mol kg−1 from emf from the bi-ISE cell without liquid junction:ISE-Na|NaCl(mA), NaBF4(mB)|ISE-ClThe activity coefficients were fit to the Harned, Scatchard, Pitzer and Lim-HOLL models and compared to those of similar systems such as NaCl + NaClO4 + H2O and NaCl + NaNO3 + H2O. Other related magnitudes, such as the activity coefficients in trace quantities, osmotic coefficients, activity of water, and change in excess Gibbs energy of mixing, were evaluated and discussed in terms of ion–ion and ion–solvent interactions.
