One approach to determine the reliability of geochemical codes is to take well-defined input data and compare the output from several different codes. For comparison of speciation results, Nordstrom et al. (1979) compiled a seawater test case and a river-water test case, i.e., seawater and river-water analyses that were used as input to 14 different codes. TTie results were compared and contrasted, demonstrating that the thermodynamic databases, the number of ion pairs and complexes, the form of the activity coefficients, the assumptions made for redox species, and the assumptions made for equilibrium solubilities of mineral phases were prominent factors in the results. Additional arsenic, selenium, and uranium redox test cases were designed for testing of... 

For solubility equilibrium to predict the aqueous concentration of a trace element, thermodynamic equilibrium is required and the solid phases must also be identified. In the case of oxyhydroxides and carbonates, it is reasonable to assume a close approach to equilibrium because the characteristic reaction times of dissolution of these minerals are in the range of a few days to a few hundred years (Bruno et al., 2002). For silicate phases the assumption of thermodynamic equilibrium is more problematic due to the low reaction rates compared to the residence time of waters in hydrosystems. Examples of codes and database used by modelers to calculate the speciation and the solubility of a number of trace elements can be found in Bruno et al. (2002). 

Each of the SAs is a code for a well-characterized chemical class, with its own specific mechanism of action. However, there are also general physico-chemical factors that may influence the potential reactivity of a chemical, that is, one could expect to observe compounds with structurally alerting features but that are biologically inactive because of a number of reasons, such as molecular weight, solubility, reactivity, and so on.

The application of speciation-solubility in geochemistry goes back to Garrels and Thompson (1962), who calculated the aqueous speciation in seawater and saturation states with respect to mineral solubilities. Since then, this subject has been treated extensively, and hundreds of codes are available for this kind of calculation. In principle, the concentration and activity coefficients of all aqueous species can be calculated if there are the same number of equations as unknowns. Given an equilibrium constant for each complex, plus an analysis giving the total quantity of each basis species, this is usually possible.
