When an aqueous solution of copper (II) sulphate is saturated with amm...
Answer:
Explanation:
When a solution of copper(II) sulfate is saturated with ammonia, it forms a deep blue colored compound. The compound is a complex of copper(II) ion and ammonia molecules. The complex is formed due to the coordination of ammonia molecules with copper(II) ion.
Formula of the Blue Compound:
The formula of the blue compound is [Cu(NH3)4]SO4.H2O.
Structure of the Blue Compound:
The structure of the blue compound is square planar. The central copper(II) ion is surrounded by four ammonia molecules in the equatorial plane and two oxygen atoms of sulfate ion in the axial positions. The water molecule is present in the lattice as a hydrate.
Coordination of Ammonia Molecules:
The ammonia molecules act as ligands and coordinate with the central copper(II) ion. The coordination number of copper(II) ion is four. The coordination geometry is square planar.
Formation of the Blue Compound:
When copper(II) sulfate solution is saturated with ammonia, the following reaction takes place.
CuSO4 + 4NH3 + H2O → [Cu(NH3)4]SO4.H2O
The blue compound is formed due to the coordination of ammonia molecules with copper(II) ion.
Conclusion:
The blue compound formed when copper(II) sulfate is saturated with ammonia is [Cu(NH3)4]SO4.H2O. The complex has a square planar structure and the coordination number of copper(II) ion is four.
