If an electrochemical cell was made from Nickel and Iron, which metal would serve as the cathode and which as the anode?

Answer 1

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?
