What is the oxidation state of cobalt in the [Co (NH₃)₄Cl₂]⁺ complex ion?

Question

Quizplus · Accepted Answer

The complex ion is [Co(NH3)5Cl]2+. The oxidation state of cobalt can be calculated by considering the charges of the ligands and the overall charge of the complex. Ammonia (NH3) is a neutral ligand, contributing no charge, while chloride (Cl) contributes a -1 charge. Since the overall charge of the complex is +2, and knowing that the sum of the oxidation state of cobalt and the charges of the ligands equals the overall charge, we can calculate the oxidation state of cobalt as +3.
