Question

how to find coordination number of central metal atom in (co(nh3)cl)cl2​

Answer 1

Answer:

Chlorine atoms almost always -1, therefore the counter ions (Cl2) give a net charge of -2.

Given the answer to (1.) we know [Co(NH3)5Cl] must have a +2 charge

All five NH3 ligands are neutral and the remaining Cl is -1, so Co must have an oxidation number of +3.

Summary

5 x NH3 → 0

1 x Cl → -1

1 x Co → +3

Gives the complex ion [Co(NH3)5Cl] → +2

2 x Cl → -2

Yields a final product [Co(NH3)5Cl]Cl2 → 0
