Multiple Choice – Only one answer is correct

c Reverse the Al3+ reduction reaction and change the sign. Eºoxidation + Eºreduction = Eºcell. (+1.66 V) + (+0.34 V ) = +2 V. d If we are making a cell, we would want the voltage to be positive. Remember you need a reduction half reaction AND an oxidation half reaction. Flip the half reaction that will allow you to end up with a positive ... ................
