Question
The correct order of the stoichiometries of AgCl formed when AgNO3 in excess is treated with the complexes: CoCl3.6NH3, CoCl3.5NH3, CoCl3.4NH3 respectively is
-
1 AgCl, 3 AgCl, 2 AgCl
-
3 AgCl, 1 AgCl, 2 AgCl
-
3 AgCl, 2 AgCl, 1 AgCl
-
2 AgCl, 3 AgCl, 1 AgCl
Solution
C.
3 AgCl, 2 AgCl, 1 AgCl
Complexes are respectively [Co(NH3)6]Cl3, [Co(NH3)5Cl]Cl2and [Co(NH3)4Cl2]Cl
