The equation for the anode part of the reaction is Fe^2+(aq)--> Fe^3+(aq) +1e-
Why does Fe^3+ come before Fe^2+ in the cell diagram?
Pt(s)I Fe^3+(aq), Fe^2+(aq)II

If both the reactants and products for a given half reaction are aqueous metal ions, they are written with the lowest charge closest to the salt bridge and the highest charge closer to the edge of the notation.
