Potassium ferricyanide

Description:

Potassium ferricyanide, with the chemical formula K3[Fe(CN)6], is a bright red crystalline compound commonly used in various applications, including photography, electrochemistry, and as a laboratory reagent. It is a salt formed from the combination of potassium ions and ferricyanide anions. The compound is known for its stability and solubility in water, producing a deep red solution. Potassium ferricyanide is non-toxic and is often used in the synthesis of other chemical compounds, as well as in the detection of certain metal ions due to its ability to form colored complexes. It is also utilized in the production of blue pigments, such as Prussian blue, through a reaction with ferrous ions. Despite its stability, it should be handled with care, as it can release cyanide ions under certain conditions, which are toxic. Overall, potassium ferricyanide is a versatile compound with significant importance in both industrial and laboratory settings.

Controlled Product

CAS: 13746-66-2

Potassium ferricyanide is a metal salt that has been used as a model system to study the rate constant of antimicrobial agents. It is also used in wastewater treatment and analytical methods, such as chemiluminescence. Potassium ferricyanide reacts with an electron-donating substance, such as sodium dodecyl sulfate or an organic compound containing hydroxyl groups, to form a radical anion. The radical anion can react with oxygen to form chemiluminescence. Potassium ferricyanide is also a useful reagent for analytical determination of metals such as iron and copper by complexation with chelating agents.
