Most of the investigations into surface chemistry have dealt with phenomena occurring at solid/gas or solid/vapour interfaces and solid/liquid surface phenomena have been relatively neglected. The reason for this undoubtedly lies in the easier interpretation of phenomena occurring in the former systems. However, the phenomena occurring at solid/liquid surfaces are very important from both a chemical and a physical viewpoint. Crystal growth, the dissolving of salts, electrolysis of solutions and reactions between solids and solutions, all occur at solid/liquid interfaces and although the solid and liquid states may be well understood, little is known of the species present at the surface and the reactions that these undergo.pdfen-NZAdsorptionIon exchangeMuscoviteSurface chemistryText
