The coordination number of a metal in coordination compounds is

Explain the bonding in coordination compounds in terms of Werner's postulates.

When $AgNO_3$ is added to a solution of $Co(NH_3)_5Cl_3$,the precipitate of $AgCl$ shows two ionizable chloride ions. This means

Which one is a Homoleptic complex?

In the complex $[X(SO_4)(NH_3)_5]$,the coordination number and oxidation state of $X$ are,respectively:

In the complex $K[Cr(H_2O)_2(C_2O_4)_2] \cdot 3H_2O$,the oxidation state and coordination number of the central metal ion are . . . . . . and . . . . . . respectively.
