What is the idealized chemical formula of the pigment synthesized by Johann Jacob Diesbach?
Johann Jacob Diesbach Johann Jacob Diesbach (] ) was a Swiss pigment and dye producer known for first synthesizing a blue pigment known as Prussian blue (i.e. iron blue or Berlin blue).
Cyanogen Cyanogen is the chemical compound with the formula (CN). It is a colorless, toxic gas with a pungent odor. The molecule is a pseudohalogen. Cyanogen molecules consist of two CN groups – analogous to diatomic halogen molecules, such as Cl, but far less oxidizing. The two cyano groups are bonded together at their carbon atoms: N≡C−C≡N, although other isomers have been detected. Certain derivatives of cyanogen are also called "cyanogen" even though they contain only one CN group. For example, cyanogen bromide has the formula NCBr.
