^aMasson coefficients allow molality-molarity interconversions. Values taken from ref 26.

^b Pitzer parameters allow aqueous-phase ionic activity coefficients to be estimated. Values were taken from ref 25, except Eu³⁺—NO₃⁻ was taken from ref 44.

^cMolar volumes of the species in the organic phase. Values for the inorganic ions were taken to be approximately equal to V₀.

^dTaken from ref 27.

^eValues estimated according to group contributions as described in ref 27.
