The brown - ring complex compound of iron is formulated as `[Fe(H_2O)_5(NO)]SO_4` . The oxidation state of iron is :

Options

A. l
B. 2
C. 3
D. O

Answer

B

Explanation

(b) Sum of oxidation state ofall atoms in neutral compound is zero. Let the oxidation state of iron in the complex ion `[Fe(H_2,O)_5,(NO)]^(2+) SO_(4)^(2-)` be x, then `x+5 xx 0+0 = +2`
`therefore x = + 2`
