Principle
Many metals, in particular transition elements, can form complexes with charged or neutral ligands. Complex formation reactions are equilibrium reactions. The stability of these complexes is described by the complex formation constant.
Benefits
- Stable and safe construction due to solid stand material
- High quality glassware for good results
Tasks
Determine the number of ligands of the silver amine complex with a precipitation titration from a silver salt solution.
