A chemical compound used in various applications

Sodium Ferrocyanide[edit]

Sodium ferrocyanide, also known as sodium hexacyanoferrate(II), is a chemical compound with the formula Na₄[Fe(CN)₆]. It is a yellow crystalline solid that is soluble in water and is used in various industrial applications.

Chemical Properties[edit]

Sodium ferrocyanide is a coordination compound consisting of a ferrous ion surrounded by six cyanide ions, forming a stable complex. The compound is non-toxic and is often used as an anti-caking agent in the food industry, where it is known as E535.

Applications[edit]

Sodium ferrocyanide is used in several applications:

Anti-caking agent: It is commonly added to table salt to prevent clumping.
Pigment production: It is used in the production of Prussian blue, a deep blue pigment.
Photography: It is used in the cyanotype process, a photographic printing process that produces a cyan-blue print.
Metal treatment: It is used in the case hardening of steel.

Safety[edit]

While sodium ferrocyanide is considered non-toxic, it can release hydrogen cyanide gas if exposed to strong acids. Therefore, it should be handled with care, especially in industrial settings.

Related Compounds[edit]

Sodium ferrocyanide is related to other ferrocyanides, such as potassium ferrocyanide, which have similar structures and properties.
