Uncertainties in NONLINT-SIT Calculations

In addition one can obtain the molalities and activities of all of the species in accordance with the aqueous phase model and in eqnilibrium with the solid phase or the other phases involved (solid, organic or ion exchanger). 

There are three different types of uncertainties those based in 1) the experimental data, 2) the ion-interaction parameters used in the SIT model, and 3) the Gibbs energies of the species which are not optimised. These uncertainties are briefly discnssed below.
