Learning outcomes - after studying this topic, you should be able to:

• define complex, ligand and coordinate bond
• recognize that hydrolysis of metal ions in aqueous solutions gives rise to acidic solutions and predict their relative acidity
• recognize chelate ligands, their donor atoms and the stability of their complexes
• name coordination complexes and compounds using IUPAC nomenclature
• identify isomers including structural, geometrical and optical isomerism for tetrahedral, square planar and octahedral complexes
• write down the form of the stability constant, K_stab, for a complex
• recognize and predict how the formation of stable complexes can increase the apparent solubility of salts by combining K_sp and K_stab expressions
