Calculating Solubility Using Equilibrium Chemistry


This model shows an approach for calculating the solubility of an element based on equilibrium chemistry. The mineral gibbsite, Al(OH)3 is used for the solid phase and dissolved Al-hydroxyl and Al-sulfate species are used to represent the aqueous speciation. These results are presented as a solubility curve of dissolved aluminum as a function of pH.
