The correct order of the stoichiometries of AgCl formed when AgNO3 is treated in excess with the complexes: CoCl3.6NH3, CoCl3.5NH3, CoCl3.4NH3, respectively, is:
  1. 1 AgCl, 3 AgCl, 2 AgCl
  2. 3 AgCl, 1 AgcCl, 2 AgCl
  3. 3 AgCl, 2 AgCl, 1 AgCl
  4. 2 AgCl, 3 AgCl, 1 AgCl

Solution

[Co(NH3)6]Cl3AgNO33moles of AgCl
[Co(NH3)5Cl]Cl2AgNO32 moles of AgCl
[Co(NH3)4Cl2]ClAgNO31mole of AgCl
The complexes are respectively CoNH36Cl3, CoNH35ClCl2 and CoNH34Cl2Cl.
