Metal complex formation can be used as a suitable titrimetric reaction under the following conditions:

  1. Formation of a stable complex: The metal ion must form a stable complex with the ligand used for the reaction. This ensures that the complex remains intact throughout the titration process, allowing for accurate determination of the metal ion.

  2. Formation of a colored complex: The metal-ligand complex must have a distinct color that can be easily observed and measured. This is important for endpoint detection during the titration process.

  3. Formation of a water-soluble complex: The metal-ligand complex must be water-soluble to ensure that it remains in solution during the titration process.
