In the compound K4[Fe(CN)6], the oxidation state of iron and its coordination number, respectively, are ________.

Question

Quizplus · Accepted Answer

The compound is made up of a Fe(CN)6 complex ion with a -4 charge, coordinated to four K+ ions. Since the complex ion has a -4 charge and each CN- ion has a -1 charge, the oxidation state of Fe must be +2 to balance the charge. The coordination number of Fe is 6, because there are six ligands bonded to it.
