Iron (+II) is one of the most important ...

Iron (+II) is one of the most important oxidation states, and salts are called ferrous salts. Most of the Fe (+II) salts are pale green and contain `[Fe(H_2O)_6]^(2+)` ion. Fe (+II) compounds are easily oxidised by air. and so are difficult to obtain pure `Fe^(2+)` form many complexes like `K_3[Fe(CN)_6]`
Anhydrous `FeCl_2` is made by

A

`K_2Fe(Fe(CN)_6]`

B

`Fe_(4)[Fe(CN)_6]_3`

C

`Fe[Fe(CN)_6]`

D

`Fe_(3)[Fe(CN)_6]_2`

Text Solution

Verified by Experts

The correct Answer is:
D
`K_3 [Fe(CN)+6] + Fe^(+2) rarr Fe_4[Fe(CN)_6]`
