Chemistry - Coordination Chemistry Question with Solution | TestHub

Complex compounds contains two different metallic elements but give test only for one of them. Because complex ions such as [Fe ${(\mathrm{CN}{)}_6]}^{4-}$ of ${\mathrm{K}}_4\left[\mathrm{Fe}(\mathrm{CN}{)}_6\right],$ do not dissociate into Fe ${}^{2+}$ and $\mathrm{CN}$ -ions.
