Oxidation number of cobalt in [Co(NH3)6]Cl2Br is-​

Answer 1

Oxidation number of cobalt in [Co(NH3)6]Cl2Br is-​

Explanation:

As there are 6 ammonia ligands which are neutral and hence carry no charge. The chlorine ligands carry a charge of -1 each and thus they have -3 charge on them. But as the molecule in whole is a neutral the coordination sphere must carry a charge of +3. So, the oxidation state of Co is +3.

Answer 2

Answer:

oxidation no of cobalt is = +3
