4 CoCl2 + 4 NH4Cl + 20 NH3 + O2 → 4 [Co(NH3)6]Cl3 + 2 H2O
This is an acid-base reaction (neutralization): NH4Cl is an acid, NH3 is a base.
This is a complexation reaction: [Co(NH3)6]Cl3 is the formed complex.
This is an oxidation-reduction (redox) reaction:
4 CoII - 4 e- → 4 CoIII (oxidation)
2 O0 + 4 e- → 2 O-II (reduction)
CoCl2 is a reducing agent, O2 is an oxidizing agent.
Reactants:
- CoCl2 – Cobalt(II) chloride
- NH4Cl – Ammonium chloride
- NH3
