Standard Cell Potential

[Tiffany Wu 1K]

For the reaction, 2H+(aq) + 2e- yields H2(g), why is the standard cell potential 0?

[Christian Hardoy 3F]

The standard cell potential is 0 for this reaction because the standard cell potential of a hydrogen electrode is the standard with which we analyze all other cell potentials. In order to compare cell potentials we need a standard reference point. That standard reference point is that equation's cell potential.

I am confused as to the difference between cell potential and reduction potential. Can someone explain it to me? Thanks

[Cyianna 2F]

Cell potential is the difference between a redox reaction and an oxidation reaction. Redox potential only consists of the reduction from the half reaction in the cathode.

It' s zero because we use the reaction of hydrogen as a reference to calculate the potential of other redox reactions.
