Inorganic Chemistry of Main Group Elements: Experiment on the Preparation of Potassium Hexacyanoferrate(III)
Step-by-Step Details
Materials:
Potassium ferrocyanide (K4[Fe(CN)6]) Iron(III) chloride (FeCl3)
Distilled water Funnel
Filter paper Vacuum filtration apparatus
Procedure:
1. Dissolve 10 g of potassium ferrocyanide in 100 mL of distilled water in a beaker.
2. Add 10 g of iron(III) chloride to 100 mL of distilled water in a separate beaker.
3. Slowly add the iron(III) chloride solution to the potassium ferrocyanide solution while stirring constantly.
4. A dark blue precipitate of potassium hexacyanoferrate(III) (K4[Fe(CN)6]) will form immediately.
5. Filter the precipitate using a funnel and filter paper.
6. Rinse the precipitate thoroughly with distilled water.
7. Dry the precipitate in an oven at 100°C.
Key Procedures
The reaction between potassium ferrocyanide and iron(III) chloride is a precipitation reaction. The product, potassium hexacyanoferrate(III), is a highly insoluble compound. The use of a funnel and filter paper allows for the separation of the precipitate from the excess reagents and water.
* Drying the precipitate in an oven removes any residual water and ensures the purity of the product.
Significance
This experiment demonstrates the formation of a brightly colored precipitate that can be used to study the chemistry of iron complexes and the precipitation reactions of transition metal ions. The product, potassium hexacyanoferrate(III), has industrial applications as a colorant and in the production of Prussian blue, a pigment used in paints and dyes.
