Chemical formula for in iron(III) hexacyanoferrate(II) is
A
`Fe[Fe(CN)_(6)]`
B
`Fe_(2)[Fe(CN)_(6)]`
C
`Fe_(4)[Fe(CN_(6)]_(3)`
D
`Fe[Fe(CN_(6)]_(3)`
Text Solution
Verified by Experts
The correct Answer is:
C
Cation is `Fe^(3+)` and anion is `[Fe(CN)_(6)]^(4-)`, then charge balance b/w cation and anion. `4xxFe^(3+)=3xx[Fe(CN)_(6)]^(4-)` `:.Fe_(4)[Fe(CN)_(6)]_(3)`
