H2 Cell Potential

Postby Nickolas Manipud 1C » Thu Mar 15, 2018 5:30 pm

The book says that 2H+ + 2e- ---> H2 has a standard cell potential of "0, by definition." Why is this so?

In order to define standard potentials of electrodes, we need a reference. Therefore, we defined the standard potential of a hydrogen electrode to be 0 and then used it to define the standard potentials of all other electrodes.
