The expression for calculating the change in real Gibbs energy was deducted. Heterogeneous systems with simultaneous reactions involving aluminium soluble and insoluble (minerals) species have been investigated. Comparisons of thermodynamic stability of Al oxysulfate minerals and gibbsite were carried out. The developed approach for calculating the Gibbs energy may be successfully applied for the prediction of complex chemical processes in soil.enaluminium mineralscomplex formationGibbs energythermodynamic stabilityThermodynamic calculations of complex chemical equilibria in soils containing aluminium mineralsCalcule termodinamice ale echilibrelor chimice complexe în soluri care conțin minerale de aluminiuArticle2069-8275
