Ligand exchange reactions in transition metal complexes
The ligands in a transition metal complex can be exchanged e.g. ammonia ligands replacing water ligands. This happens either because

What is a complex ion?
d-block metal cations readily form complexes with ligands – neutral molecules such as water or anions such as the chloride
