Question

The correct order of the stoichiometries of AgCl formed when A g N O 3 in excess is treated with the complexs C o C l 3 6 N H 3 , C o C l 3 . 5 N H 3 , C o C l 3 . 4 N H 3 respectively is

Using Werner theory it is clear that only primary valencies are ionisable or precipitable
$[C o (N H_{3})_{6}] C l_{3} \overset{3 A g N O_{3}}{\to} [C o (N H_{3})_{6}]^{3 +} + 3 A g C l$
$[C o (N H_{3})_{5} C l] C l_{2} \overset{2 A g N O_{3}}{\to} [C o (N H_{3})_{5} C l]^{2 +} + 2 A g C l$
$[C o (N H_{3})_{4} C l_{2}] C l \overset{A g N O_{3}}{\to} [C o (N H_{3})_{4} C l^{+}] + A g C l$
Hence, 3, 2, 1 AgCl are formed.
