Concentration Cells

Postby Nasir_Ahmed » Mon Feb 13, 2017 2:30 pm

In the course reader, it says that when you have a galvanic or voltaic cell with the same components at different concentrations, the standard reduction potential will always be 0 V. Why is that?

Standard reduction potentials measure the potential difference between two electrodes. If the electrodes are made of the same material there is no difference. The different concentrations of the solutions only affect E cell, not standard E cell. See the diagram on page 53 in the course reader.

Thank you!
