Strategy:
 Similar to potential cycle addition, relate standard potentials via  to find the value of the unknown oxidation potential.

Step 1: Set up equations
1. , 
2. , 
Target (Oxidation):

Step 2: Combine steps
The target reaction is effectively:  inverted.
Alternatively, Reduction  is: .
.
.

Step 3: Oxidation potential
Oxidation potential .
Comparing with , we get .
