WebMay 10, 2024 · What you see in a test tube is: The main equilibrium involved in the ligand exchange reaction is: [ Cu ( H 2 O) 6] 2 + + 4 NH 3 ↽ − − ⇀ [ Cu ( NH 3) 4 ( H 2 O) 2] 2 + + 4 H 2 O. The color of the deep blue complex is so strong that this reaction is used as a sensitive test for copper (II) ions in solution.
