Question

Suppose that scientists had chosen the Cu2+CuC u^{2+} | Cu half-cell as a standard instead of the H+H2H^+ | H_2 half-cell? What would the potential of the hydrogen electrode be if the copper electrode were the standard? How would the relationships among the standard reduction potentials change?

Step 1
1 of 2

The reaction Cu2++2 eCuCu^{2+} + 2 \ e^- \rightarrow Cu has standard reduction potential of E0=0.3419 VE^0 = 0.3419 \ V. This value is based on the hydrogen as the reference electrode.

If copper was used as the standard electrode, it would take the value of zero. Hydrogen would have a standard reduction potential of E0=0.3419 VE^0=-0.3419 \ V.

The standard reduction potential will change 0.3419 V0.3419 \ V back. Making the copper as the standard electrode will only change the reference point. If you solve for the potential difference between the half-cells, the answer will still yield the same answer. It is so much like counting starting from 0 to 5 and counting from 10 to 15. You will have a different starting and ending point but you will still have the same number and way to count numbers.
