Question

[Fe(H2O) 5NO]SO4 oxidation no. Of Fe

Answer 1

Answer: Oxidation number of central metal atom i.e. Fe is +3.

Explanation:

when this coordinate compound is dissolved in water then ion will formed i.e. [ Fe (H2O)5 (NO) ] ^2+ and SO4 ^2- ..

The oxidation no. of H2O = O

The oxidation no. of NO = -1

The oxidation no. of SO4 = +2

x+(0)5+(-1) = +2

x + 0 - 1 = +2

x = +2 +1

x = +3

Hence the oxidation no. of Fe is + 3.
