A cation can be bioavailable if present as aquo ion or complexed. This research studies aqueous solutions at equilibrium. Identification of species means qualitative analysis, determination of stability constants and field of existence is quantitative. Reagent concentration is widely varied and the most number of parameters at equilibrium is measured . To obtain thermodynamic data, the "constant ionic medium", is adopted. It allows to assume as constant the reagents activity coefficients in spite of variation of their concentrations replacing till to 15% of the ions of ionic medium.
