Vedclass · Answer

(C) The primary valency corresponds to the oxidation state of the central metal ion,and the secondary valency corresponds to the coordination number.For the complex $[Co(C_2O_4)_2(H_2O)_2]^{-}$:Let the oxidation state of $Co$ be $x$.$x + 2(-2) + 2(0) = -1$$x - 4 = -1$$x = +3$.Thus,the primary valency is $3$.The coordination number is the total number of donor atoms attached to the central metal ion.$C_2O_4^{2-}$ is a bidentate ligand ($2 	imes 2 = 4$ donor atoms) and $H_2O$ is a monodentate ligand ($2 	imes 1 = 2$ donor atoms).Total coordination number $= 4 + 2 = 6$.Thus,the secondary valency is $6$.

What is the primary and secondary valency of the central metal in the complex $[Co(C_2O_4)_2(H_2O)_2]^{-}$?
