The compound K₃[Fe(CN)₆] is used in calico printing and wool dyeing. What is its systematic name? A) potassium iron(III) hexacyanate B) tripotassium iron(III) hexacyanate C) potassium hexacyanoferrate(III) D) potassium hexacyanideferrate E) tripotassium hexacyanoiron(III)

Question

Quizplus · Accepted Answer

The compound contains a hexacyanoferrate(III) complex ion, which is named by combining the name of the metal ion (iron) with the ligand name (hexacyanide), and indicating the oxidation state of the metal ion (III) in parentheses. The potassium ions are simply named as cations, so the systematic name of the compound is potassium hexacyanoferrate(III).
