When `AgNO_3` solution is added in excess to 1M solution of `CoC1_3 cx NH_3` one mole of AgCl is formed ? What is the value if 'X'?

Options

A. 1
B. 4
C. 3
D. 2

Answer

(a)

Explanation

`[CoCl_3xx Nh_3 +AgNO_3 to Agcl ]`
since 1 mole of Agcl is formed only one Clis present outside the coordination sphere i.e, `[CoCl_2xx NH_3] Cl`
coordiantion number Co is 6. As Co is already bonded to two Cl atoms, it can bond to another four `NH_3` molecules
Therefore X= 4.
