Answer 2

Given:

The given complex is $[Co(NH_3)_2(H_2O)_2Cl_2]^+$.

To find:

The oxidation number and coordination number of Co.

Solution:

The given complex is $[Co(NH_3)_2(H_2O)_2Cl_2]^+$.

Let the oxidation state of Co is x.

The charge of water is 0, ammonia is 0 and Cl is -1.

Thus, the oxidation number of Co is as follows-

$x + 0 + 0 + 2 \times ( - 1) = + 1 \\ x = + 3$

Thus, the oxidation number of Co is +3.

The coordination number of Co is given as the ligands attached to it. Here six ligands are attached to Co. So, the coordination number of Co is 6.

Thus, the oxidation number of Co is +3 and the coordination number of Co is 6.
