According to Werner's theory

C o C l_{3} \cdot 6 N H_{3} \to [C o (N H_{3})_{6}]^{3 +} 3 C l^{-}

C o C l_{3} \cdot 5 N H_{3} \to [C o (N H_{3})_{5} C l]^{2 +} 2 C l^{-}

C o C l_{3} \cdot 4 N H_{3} \to [C o (N H_{3})_{4} C l_{2}]^{+} C l^{-}

When

A g N O_{3}

in excess is treated with these complexes then following reactions takes place :

[C o (N H_{3})_{6}]^{3 +} 3 C l^{-} + (Excess) A g N O_{3} \to 3 A g C l + [C o (N H_{3})_{6}]^{3 +}

[C o (N H_{3})_{5} C l]^{2 +} 2 C l^{-} + (Excess) A g N O_{3} \to 2 A g C l + [C o (N H_{3})_{5} C l]^{2 +}

[C o (N H_{3})_{4} C l_{2}]^{+} 2 C l^{-} + (Excess) A g N O_{3} \to A g C l + [C o (N H_{3})_{4} C l_{2}]^{+}
