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
