उत्तर
The oxidation state of cobalt ion in the complex [Co(NH3)5Br]SO4 is +3.
Explanation:
We know, sulphate ion has a charge –2
i.e., \[\ce{SO^{2-}_4}\]
Then, [Co(NH3)5Br]2+
The oxidation state of NH3 = 0
The oxidation state of Br = –1
Let the oxidation state of Cobalt ion is x
Then, x + (3 × 0) × 5 + (–1) = +2
⇒ x – 1 = +2
⇒ x = +3
Therefore the oxidation state of cobalt ion is +3.
