Prediction of the ionic composition of a soil solution which is at equilibrium with an exchanger phase is one of the main problems in soil chemistry. To date the most practical way to achieve this objective is to adopt a thermodynamic approach for the study of soil-solution systems. As of 1979 more than 300 sets of data on cation exchange on various clay minerals and soils had been subjected to thermodynamic analysis (Bruggenwert and Kamphorst 1979).
