In order to help determine if the equilibria reached by soil mineral mixtures is that predicted on the basis of single minerals, two kaolinite samples were equilibrated individually and also with gibbsite of known stability. One set of samples was equilibrated from undersaturation, the other from supersaturation. Samples were analyzed periodically and equilibrium values obtained by extrapolation to infinite time. The solution ion compositions found were those predicted on the basis of the solubilities of the individual minerals.
