Choose the half reaction for A1³+ and Al as your reference point and assign a value of 0 V for this half- reaction. To make the standard cell potential for the Al³+/Al half-reaction equal to zero, you would have to add 1.66 V to the accepted standard reduction potential. To adjust all the reduction potentials to the new reference, you add 1.66 V to each value.

![Choose the half reaction for A1³+ and Al as your reference point and assign a value of 0 V for this half-
reaction. To make the standard cell potential for the A1³+/Al half-reaction equal to zero, you would have to
add 1.66 V to the accepted standard reduction potential. To adjust all the reduction potentials to the new
