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

1.	What is the oxidation state of `Co[Co(H_(2)O)_(5)Cl]^(2+)` ?A. `+2`B. `+3`C. `+1`D. `+4`
Answer» Correct Answer - C 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)`.
