What is Ex-05 - Test For Cations With Sodium Hydroxide and Ammonia about?

The experiment focuses on identifying cations through their reactions with sodium hydroxide (NaOH) and ammonia (NH₃), leading to the formation of colored precipitates. Transition metals exhibit distinct color changes and solubility behaviors, which facilitate their identification. Key observations include the amphoteric nature of zinc, the insolubility of ferric ions in excess reagents, and the formation of a deep blue complex with copper ions in the presence of excess ammonia.
