Abstract
THE interaction between hydrogen clays and neutral salts gives rise to H+ and A1+++ and, in a secondary measure, Fe+++ ions in the salt extracts. The mechanism of this reaction has been the subject of much discussion1–8. Some investigators1–5 consider that the acid liberated by the salt dissolves A1+++ and Fe+++ ions from the sesquioxides present in the hydrogen clay, while others6–8 postulate a direct exchange of A1+++ and Fe+++ ions for the cations of the added salt.
