Acidic ferric chloride solution on treatment with excess of potassium ...
Explanation:
When an acidic ferric chloride solution is treated with an excess of potassium ferrocyanide, it results in the formation of a Prussian blue colored colloidal species. This reaction can be represented by the following equation:
FeCl3 + 6K4[Fe(CN)6] → KFe[Fe(CN)6] + 6KCl
The correct answer is option 'D', which represents KFe[Fe(CN)6] as the colloidal species formed.
Explanation in detail:
1. Formation of Ferric Chloride:
When ferric chloride (FeCl3) is dissolved in water, it dissociates into Fe3+ ions and Cl- ions. This forms an acidic solution due to the presence of H+ ions from the dissociation of water.
FeCl3 → Fe3+ + 3Cl-
2. Formation of Potassium Ferrocyanide:
Potassium ferrocyanide (K4[Fe(CN)6]) is a yellow crystalline solid that dissociates in water to form K+ ions and the ferrocyanide ion ([Fe(CN)6]4-).
K4[Fe(CN)6] → 4K+ + [Fe(CN)6]4-
3. Reaction between Ferric Chloride and Potassium Ferrocyanide:
When an acidic ferric chloride solution is treated with an excess of potassium ferrocyanide, a redox reaction occurs. The Fe3+ ions from ferric chloride are reduced to Fe2+ ions, while the ferrocyanide ions are oxidized to ferricyanide ions.
Fe3+ + [Fe(CN)6]4- → Fe2+ + [Fe(CN)6]3-
This reaction results in the formation of a Prussian blue colored precipitate, which is the colloidal species. The Prussian blue compound has the chemical formula KFe[Fe(CN)6].
4. Explanation of the Correct Answer:
Option 'D' represents KFe[Fe(CN)6], which is the correct answer. The other options (a, b, and c) do not represent the correct chemical formula for the Prussian blue colloidal species formed in the reaction.
