[Fe(CN)6]4-is an example of a _______a)Coordination compoundb)Complex ...
Coordination compound

Coordination compounds are compounds that contain a central metal ion or atom coordinated to one or more ligands. Ligands are typically ions or molecules that have at least one pair of electrons to donate to the metal ion. The coordination number of the metal ion is determined by the number of ligands attached to it.

Complex ion

A complex ion is an ion formed from the central metal ion and the ligands. It represents the central metal ion and the ligands together as a single species. The charge of the complex ion is equal to the charge of the central metal ion plus the charges of the ligands.

Double salt

A double salt is a compound that contains two different cations or anions that are held together by ionic bonds. These salts have a definite ratio of the two ions and can be separated into their individual ions by dissolution in water.

Complex salt

A complex salt is a compound that contains a complex ion along with other ions. It is formed from the reaction between a metal salt and a ligand. The complex ion is responsible for the coordination of the ligands, while the other ions are present to balance the charges.

In the given compound [Fe(CN)6]4-, the coordination complex ion is [Fe(CN)6]4-. The central metal ion is Fe(iron), which is coordinated to six CN(cyanide) ligands. The coordination number of the iron ion is 6, as it is coordinated to six ligands.

Therefore, the correct answer is option B) Complex ion, as [Fe(CN)6]4- represents the complex ion formed by the coordination of the iron ion to the cyanide ligands.
