Is the Fe dipping into a ferrous or a ferric solution? Let' say Fe^2+, Then
Fe(s) + Ni^2+(aq) ==> Fe^2+(aq) + Ni(s)
Oxidation occurs at the anode; reduction occurs at the cathode. So which is oxidized and which is reduced?
If an electrochemical cell was made from Nickel and Iron, which metal would serve as the cathode and which as the anode?
