ABSTRACTThe hydration status of a Na-Ca montmorillonite was investigated by anion-exclusion volume measurements as a function of the ionic strength of the free solution and of the adsorbed calcium percentage.The marked curvature of the relationship between the exclusion volume and the adsorbed calcium percentage at values of the latter comprised between 80 and 85 percent decreased markedly with increasing ionic strength towards an approximately linear relationship.
