Solution
The coordination compound will be a complex compound that has a structural formula of - [Co(NH₃)₆]Cl₃ and its IUPAC name is - Hexaaminecobalt (III) chloride.
In a series of compounds of cobalt(III) chloride with ammonia, it was found that some of the chloride ions could be precipitated as AgCl on adding excess silver nitrate solution in cold but some remained in solution.
1 mol CoCl3.6NH3 (Yellow) gave 3 mol AgCl
1 mol CoCl3.5NH3(Purple) gave 2 mol AgCl
1 mol CoCl3.4NH3(Green) gave 1 mol AgCl
1 mol CoCl3.4NH3(Violet) gave 1 mol AgCl
