Ferric ammonium ferrocyanide

Description:
Ferric ammonium ferrocyanide, commonly known as Prussian blue, is an inorganic compound with the formula Fe₃[Fe(CN)₆]₂. It is characterized by its deep blue color, which is a result of the presence of iron in both the ferric (Fe³⁺) and ferrous (Fe²⁺) states, coordinated with cyanide ligands. This compound is typically found as a stable, insoluble pigment and is used in various applications, including art, dyeing, and as a biological stain. Prussian blue exhibits unique properties such as high stability, non-toxicity, and the ability to absorb certain heavy metals, making it useful in medical treatments for heavy metal poisoning. It has a crystalline structure and is often used in the production of inks and paints due to its vibrant hue. Additionally, it has applications in environmental remediation, particularly in the removal of cesium and thallium from contaminated water. Overall, ferric ammonium ferrocyanide is notable for its color, stability, and versatility in both industrial and medical fields.
