Specify the ox:dation numbers of the metals in the following coordination entitịes.

Explanation

a) .[Co(H_2 O)(CN)(en)_2]^3 *-. In the complex .H_2 O.
and (en) are neutral ligands. Let the ox. no. of Co be X. .x+(-1)=+2.
.therefore^prime x=+3.
ox. no. of .Co=+3.
b) .[P CCI_4 ~J^-.. Let the .0 x .. no. of .Pt=x.
.because therefore x+4(-1)=-2.
.x=4-2=+2.
.therefore o x., no. of .dot P t=+2.
