Brown colour of the complex [Fe(H(2)O)(5...

Brown colour of the complex `[Fe(H_(2)O)_(5)(NO)]SO_(4)` is due to C. T. spectrum which causes momentary change in oxidation state. Find out oxidation state of Fe in this complex.

A

The brown ring complex is formed between nitric oxide (formed as a result to reduction of the nitrate ion by the `Fe^(2+)` ions) and `Fe^(2+)` ions

B

Iron and `NO` both have `+1` charge

C

The complex species can be represented as `[Fe^(+)(H_(2)O)_(5)(NO)]^(2+)`

D

Iron has `+2` oxidation state and `NO` is neutral
