Determine the oxidation state of the metal ion in [co(nh3)5br]2+. express your answer as an integer.
Zanzabum
                                           [Co(NH₃)₅Br]²⁺

Ligands and charges on them,

                             5 × NH₃  =  5 × 0  =  0

                             1 × Br⁻¹  =  1 × -1  =  -1

Charge on sphere  =  +2

So, putting values in equation,

                                       Co + (0)₅ - 1  =  +2

                                       Co + 0 - 1  =  +2

                                       Co - 1  =  +2

                                       Co  =  +2 + 1

                                       Co  =  +3

Result:
           Oxidation state of Co in [Co(NH₃)₅Br]²⁺ is +3.
