Complexes

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, Kstab, for a complex
  • recognize and predict how the formation of stable complexes can increase the apparent solubility of salts by combining Ksp and Kstab expressions
