WebJan 23, 2024 · The pigment Prussian blue consists of iron cations, cyanide anions, and water. The empirical formula—minus the water of crystallization—is Fe 7 (CN) 18. This seems odd with respect to the iron oxidation state until you learn that the complex contains Fe (II) and Fe (III). Thus, the formula that gives a truer idea of its composition is Fe 4 ...

Suggest a … In chemistry, a cyanide (from Greek kyanos 'dark blue') is a chemical compound that contains a C≡N functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. In inorganic cyanides, the cyanide group is present as the cyanide anion C≡N. This anion is … See more The cyanide ion C≡N is isoelectronic with carbon monoxide C≡O and with molecular nitrogen N≡N. A triple bond exists between C and N. The negative charge is concentrated on carbon C. See more Protonation Cyanide is basic. The pKa of hydrogen cyanide is 9.21. Thus, addition of acids stronger than hydrogen cyanide to solutions of cyanide salts releases hydrogen cyanide. Hydrolysis See more Many cyanides are highly toxic. The cyanide anion is an inhibitor of the enzyme cytochrome c oxidase (also known as aa3), the fourth complex of the electron transport chain found … See more Cyanide is quantified by potentiometric titration, a method widely used in gold mining.
