In this topic we explore equilibria involving ligand exchange reactions.

After working through this topic you will be able to:

  • understand what is meant by a complex ion and be able to write equations to represent the equilibria involved in ligand replacement reactions;
  • write expressions for stability constants and understand how stability constants are affected by the chelate effect;
  • reflect on what students find difficult about ligand exchange reactions and devise ways of helping them develop their understanding of these changes; and
  • help students appreciate why ligand exchange reactions are important.
