Complex formation equilibrium / complex formation constant

Product No: P3031001

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.

Tasks

Determine the number of ligands of the silver amine complex with a precipitation titration from a silver salt solution.
