Let x be the number of five-membered chelate rings in [Co(EDTA)]⁻ and y the number of chelate rings in [Cr(en)₃]³⁺. Let z be the average oxidation number of Fe in Prussian blue, Fe₄[Fe(CN)₆]₃. Find xy/z to two decimal places.
Answer:
5.83
Solution:
EDTA binds through two N and four O: four N–CH₂–COO rings plus the N–C–C–N ring, so x = 5. y = 3. In Fe₄[Fe(CN)₆]₃, four Fe³⁺ and three Fe²⁺ give z = (12 + 6)/7 = 18/7. xy/z = 15 × 7/18 = 5.83.
