Expert solve this find net oxidative change
We are given that the ion is [Fe(CN)6]4-. This is a complex ion in which the central metal atom is iron (Fe) and is surrounded by six CN ligands. The cyanide ion is a negatively charged ligand which has a charge of -1. The overall charge on the complex ion is -4. Let us assume that the charge on Fe is z. Therefore we have
z + 6 (-1) = -4
z - 6 = -4
Thus z = 2
So the charge on Fe is +2.
But In the given equation
Hope this information clears your doubt.
