Here's a breakdown of the formula:
* Fe3+: This represents the ferric ion (iron in the +3 oxidation state).
* [Fe(CN)6]4-: This represents the ferrocyanide ion, which is a complex ion consisting of a central iron atom (Fe2+) bonded to six cyanide ions (CN-).
The overall formula reflects the fact that there are four ferric ions (Fe3+) for every three ferrocyanide ions ([Fe(CN)6]4-) to balance the charges.
