Question
The two solutions are contained (no dilution) in a single beaker with a saturated calomel electrode and an inert
electrode (e.g., Pt) immersed in the solution.
Relevant information:
Cr0,/Cr*:
Fe*/Fe*:
For SCE:
E° = +1.33 V
E° = +0,77 V
Erer +0.244 V
Cr,O, + 6Fe" +14H"
2Cr + 6Fe* + 7H;0
The reaction quickly reaches equilibrium. What is the potential of this cell?
