Experiment: Synthesis of Prussian Blue Pigments
Significance:

Prussian blue is an inorganic pigment with a rich history and applications in art, medicine, and materials science. This experiment showcases the advancements in inorganic chemistry by providing a simple and illustrative method for synthesizing this iconic blue pigment.


Materials:

  • Potassium hexacyanoferrate(III) (K4[Fe(CN)6])
  • Iron(II) chloride (FeCl2)
  • Hydrochloric acid (HCl)
  • Distilled water

Step-by-Step Procedure:

  1. Dissolve the reactants:

    • Dissolve 0.5 g of K4[Fe(CN)6] in 100 mL of distilled water.
    • Dissolve 0.25 g of FeCl2 in 50 mL of distilled water.

  2. Acidify the FeCl2 solution:

    • Add 2-3 drops of concentrated HCl to the FeCl2 solution.
