In the previous chapters, equations have been derived for the estimation of the total potential anomalies and the preliminary data treatment for the equilibrium systems HY – BYz(B) – AyL – AY. In these calculations, the species Bz(B)+, Ly–, A+, Y– and H+ were assumed to be present. The potential functions Q(H, V)V with V = [Bz(B)+], [H+], [Ly–], \(\Delta\)cY or / and \(\Delta\)cA have been estimated, partly by conductivity measurements and partly by the use of known slope functions. Having these functions, log10 h can be calculated by successive approximations. Then preliminary chemical models and equilibrium constants can be established with the help of a curve-fitting computer program. From these results, one can see if the presence of the metal ion complexes is negligible or not. If they are not negligible, new treatment of emf data must be planned. This can take place through several steps.
