Analytical data on water samples from acid sulfate soils and acid mine spoils indicate that the upper limit of dissolved Al is regulated by a basic aluminum sulfate with the stoichiometric composition AlOHSO 4 . The observed solubility relationship, pAl + pOH + pSO 4 = 17.23, can be useful in defining environmental conditions in terms of pH and dissolved sulfate for the occurrence of Al concentrations toxic to plants.
