A coordination complex compound of cobalt has the molecular formula containing five ammonia molecules, one nitro group and two chlorine atoms for one cobalt atom. One mole of this compound produces three mole ions in an aqueous solution. On reacting this solution with excess of AgNO3 solution, we get two moles of AgCl precipitate. The ionic formula for this complex would be
[Co(NH3)5(NO2)]Cl2
[Co(NH3)5Cl] [(NO2)]Cl2
[Co(NH3)4(NO2)]Cl] [NH3)Cl]
[Co(NH3)5] [(NO2)2Cl2]
