Formation of Prussian Blue
Prussian blue is a deep blue pigment formed when iron(III) ions (Fe3+) react with ferrocyanide ions (Fe(CN)6)4-. This reaction is significant in inorganic chemistry and is used as a qualitative test for Fe3+ ions.
Reaction Overview
- When potassium ferrocyanide (K4[Fe(CN)6]) is added to a solution containing Fe3+, it leads to the formation of a complex.
- The reaction can be represented as follows:
Fe3+ + [Fe(CN)6]4- → Prussian blue precipitate.
Correct Compound Formation
- The correct compound formed in this reaction is Fe4[Fe(CN)6]3. This is represented as:
- Fe4[Fe(CN)6]3 is a complex where four Fe3+ ions coordinate with three [Fe(CN)6]4- ions.
- This stoichiometry ensures that the charges balance out, resulting in an insoluble blue precipitate.
Other Options Explained
- Option A: [Fe(H2O)6]2[Fe(CN)6] - This represents a different complex and does not correspond to the formation of Prussian blue.
- Option B: Fe2[Fe(CN)6]2 - Here, the stoichiometry does not support the formation of Prussian blue.
- Option C: Fe3[Fe(OH)2(CN)4]2 - This involves hydroxide ions and does not form Prussian blue.
Conclusion
- The formation of Prussian blue is a classic example of a coordination complex, demonstrating the interaction of transition metals with ligands, specifically ferrocyanide ions.
- Thus, the correct answer to the question is indeed option D: Fe4[Fe(CN)6]3.
