Prussian blue: History, Applications & Research

Prussian blue (also known as Berlin blue, Brandenburg blue, Parisian and Paris blue) is a dark blue pigment produced by oxidation of ferrous ferrocyanide salts. It has the chemical formula Fe43. It consists of Fe3+ cations, where iron is in the oxidation state of +3, and 4− anions, where iron is in the oxidation state of +2, so, the other name of this…
