(b) Surface complexation is an important factor in cation exchange. Explain, including using sketches, the terms “inner-sphere surface complexation" and "outer-sphere surface complexation”. Your answer should include the relative strength of interactions. [6 marks] (c) Consider an aqueous solution, with pH less than 9, containing Mg2+ ions. This solution is in contact with a clay surface. What type of surface complex (inner-sphere or outer-sphere) would you expect Mg2+ to form and why? [4 marks]
