A concentration cell is constructed by using the same half-reaction for both the cathode and anode.What is the value of standard cell potential, E°, for a concentration cell that combines a silver anode in contact with 0.10 M silver nitrate and a silver cathode in contact with 3.0*10^-5 M silver nitrate?
(E° =0.80 V for Ag /Ag ⁺)

Question

Quizplus · Accepted Answer

The standard cell potential (E°) for a concentration cell is always 0.00 V because it is defined under standard conditions where the concentrations of the reactants and products are the same (1 M), leading to no net cell potential difference.
