About Potassium Ferrocyanide Trihydrate Lab Grade
Potassium Ferrocyanide, also known as Potassium Hexacyanoferrate(II), Tetrapotassium
Ferrocyanide Trihydrate, and Yellow Prussiate, is often available as Trihydrate of Potassium
Hexacyanoferrate(II) having the chemical formula K4Fe(CN)6-3H2O or C6H6FeK4N6O3. It appears
as odorless lemon-yellow crystalline granules or powder and is soluble in Water at ambient
conditions. When heated to decomposition it emits toxic fumes of Nitrogen Oxides (NOx), Carbon
Monoxide (CO), Carbon Dioxide (CO2), Hydrogen Cyanide (Hydrocyanic Acid), and Heavy
metals. It can be produced on an industrial scale by reacting Hydrogen Cyanide, Ferrous Chloride,
and Calcium Hydroxide. This leads to the formation of Ca2[Fe(CN)6]-11H2O, which is then
combined with Potassium salts to precipitate the mixed Calcium-Potassium salt CaK2[Fe(CN)6].
This salt is finally treated with Potassium Carbonate to give the final product. Lab grade chemicals
possess reasonable purity but do not comply with any official standard for quality or purity like
the ACS Grade, the USP Grade, or the FCC Grade. The Lab Grade is also known as Laboratory
Reagent (LR) and Chemically Pure (CP). Lab Alley’s Potassium Hexacyanoferrate Trihydrate,
Lab Grade or Potassium Ferrocyanide Trihydrate, Lab Grade is recommended for educational
institutes and research labs.
