Ferric hexacyanoferrate(ii)

Ferric hexacyanoferrate(II) is a type of inorganic compound that is commonly used in various industrial applications. It is also known as Prussian blue or Berlin blue, due to its deep blue color.

Chemical Structure

Ferric hexacyanoferrate(II) is a coordination complex, which means it is composed of a central metal ion surrounded by multiple ligands. In this case, the central metal ion is iron(III) (Fe^3+), and the ligands are cyanide ions (CN^-). The overall structure is a cubic lattice, with the iron ions at the corners and the cyanide ions bridging the gaps between them.

Properties

Ferric hexacyanoferrate(II) is a crystalline solid that is insoluble in water. It has a deep blue color, which is why it is often used as a pigment in paints and dyes. It is also paramagnetic, meaning it is attracted to magnetic fields.

Applications

One of the main uses of ferric hexacyanoferrate(II) is as a pigment in paints and dyes. It is also used in the production of blueprints, due to its ability to react with ferric salts to produce a blue color. In addition, it is used in certain types of batteries, due to its ability to store and release electrons.

Safety

Ferric hexacyanoferrate(II) is generally considered safe to handle, but it can be harmful if ingested or inhaled in large quantities. It is also a potential environmental hazard, due to its ability to leach into soil and water.
