Chemistry - Redox Reactions Question with Solution | TestHub

There is no change in the oxidation number of any species in the reaction so neither oxidation nor reduction occurs here.
$4\mathrm{K}\mathrm{C}\mathrm{N}+\mathrm{F}\mathrm{e}(\mathrm{C}\mathrm{N}{)}_2\to {\mathrm{K}}_4[\mathrm{F}\mathrm{e}\left(\mathrm{C}\mathrm{N}{)}_6\right]$
