This powerpoint fully covers the following criteria –

28.5 Stability constants, Kstab

Learning outcomes
Candidates should be able to:

1. define the stability constant, Kstab, of a complex as the equilibrium constant for the formation of the complex ion in a solvent (from its constituent ions or molecules)

2. write an expression for a Kstab of a complex ([Hâ‚‚O] should not be included)

3. use Kstab expressions to perform calculations

4. describe and explain ligand exchanges in terms of Kstab values and understand that a large Kstab is due to the formation of a stable complex ion
