Ferricyanid

Ferricyanide is an inorganic anion with the chemical formula [Fe(CN)6]3−. It is a coordination complex consisting of a central iron(III) ion surrounded by six cyanide ligands. Ferricyanide is a strong oxidizing agent and is commonly used in various chemical and industrial applications.

Ferricyanide is typically prepared by the reaction of iron(III) salts with a strong base, such as sodium hydroxide, in the presence of cyanide ions. The resulting solution contains the ferricyanide anion, which can be isolated by precipitation or crystallization.

Ferricyanide is used in a variety of applications, including as a bleaching agent, a disinfectant, and a corrosion inhibitor. It is also used in the production of certain dyes and pigments. In the laboratory, ferricyanide is often used as a titrant in redox titrations.

Ferricyanide is toxic and can cause irritation to the skin, eyes, and respiratory tract. It is also a potential carcinogen, and prolonged exposure should be avoided. Proper handling and disposal procedures should be followed when working with ferricyanide.
