Abstract: Extrapolation of formation constants to zero ionic strength using “soft” modelling with partial least-squares, genetic algorithm, and artificial neural networks (ANN) methods was examined and results of individual approaches were compared. The methods allow a rapid and sufficiently accurate prediction of thermodynamic formation constants, ion-size parameters, and salting-out coefficients from experimental equilibrium data, among them the ANN method was found most reliable.
