Abstract
The effect of over 50 different solids (including sulphides, halides, oxides, metals, and non-metals) on aqueous solutions of the salts (+)589[Co(en)3]X3(X = I or ClO4) has been investigated. The degrees of racemisation, adsorption, and reduction of the complex ion have all been followed. Thermodynamic arguments are presented that help to explain the role of the anion. The catalytic efficacies of the solids have been examined in the light of Pearson's theory of soft and hard acids and bases.Keywords
