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. Reagent Grade chemicals have high purity and are best suited for analytical applications. They're important in research because of their reliable, dependable, and repeatable results. Lab Alley sells its high- quality Potassium Hexacyanoferrate Trihydrate, Reagent Grade or Potassium Ferrocyanide Trihydrate, Reagent Grade online at laballey.com in the United States of America (USA). This Lab Alley product is highly recommended for research labs and commercial uses due to its high purity.
