Inorganic Chemistry Experiment: Synthesis of Tetraamminecopper(II) Sulfate
Materials
- Copper(II) sulfate pentahydrate (CuSO4·5H2O)
- Ammonia solution (NH3)
- Distilled water
- Beaker
- Stirring rod
- Filter paper
- Funnel
Procedure
1.
Dissolve copper(II) sulfate pentahydrate in water: Dissolve 2.5 g of CuSO
4·5H
2O in 50 mL of distilled water in a beaker.
2.
Add ammonia solution: Slowly add concentrated ammonia solution to the copper sulfate solution while stirring continuously with a stirring rod. The solution will initially turn blue, then a deep blue-violet color.
3.
Formation of precipitate: As ammonia is added, a blue precipitate of tetraamminecopper(II) sulfate ([Cu(NH
3)
4]SO
4) will form.
4.
Filter the solution: Filter the precipitate using filter paper and a funnel into a clean beaker. Rinse the precipitate with cold distilled water to remove any impurities.
5.
Dry the precipitate: Spread the precipitate on a piece of filter paper and allow it to air-dry.
Key Procedures
Dissolving the copper sulfate: This step allows the copper ions to be in solution and react with the ammonia. Adding ammonia: Ammonia acts as a ligand and binds to the copper ions to form the tetraamminecopper(II) complex.
Filtering the precipitate: This step separates the tetraamminecopper(II) sulfate from the remaining solution. Drying the precipitate: This step removes any remaining water from the precipitate.
Significance
Demonstrates the formation of a complex ion ([Cu(NH3)4]2+) and its properties. Highlights the role of ligands in coordinating with metal ions.
