What is the oxidation state of `Co` in `[Co(H_(2)O)_(5)Cl]^(2+)` ?

A

`+2`

B

`+3`

C

`+1`

D

`+4`

Text Solution

Verified by Experts

The correct Answer is:
B
Since, the O.N of `SO_(4)^(2-)` is -2, therefore the total charge on the complex ion, `[Fe(H_(2)O)_(5)NO]` is +2. Since No is paramagnetic molecule, its unpaired electron is transferred to iron. As a result, NO carries +1 charge. Further, since `H_(2)O` is a neutral molecule, its O.N is zero. Putting the values of all the oxidation numbers, the O.N of Fe in the complex ion `= x+0 xx 5 + 1=2`
`:. n = +1`
Thu the O.N of Fe is +1 and the correct structure of the `|Fe(H_(2)O)_(5)NO|SO_(4)` is `|Fe^(+1)(H_(2)O)_(5)NO|SO_(4)`.
