However, as stated by Grenthe et al. [14], the variation in ñ (Baj term in [14]) values used in the Debye-Hückel term does not represent an uncertainty range, but rather indicates covariation of the parameters ñ and ε j, k) such that several different combinations of these parameters may reproduce equally well the measured mean activity coefficients of a given electrolyte.
