Reaction at cathode
Al^+3 +3e = Al in this rxn Al ion reduced in Al by taking 3 e
In galvanic cells reduction occurs at cathode
Reaction at anode
Mg = Mg^+2 + 2e in this rxn Mg is oxidized to Mg ion by loosing 2e
Because oxidation occurs at anode in these cells.
You can remember it by a trick..Red Cat...Red means reduction and Cat means cathode
