Standard Hydrogen Electrode

Postby Isabel Gutierrez 2G » Sat Feb 04, 2017 11:38 pm

Why is the standard potential of a hydrogen electrode always zero?

It's defined as the reference point and set to 0 so that the reduction potentials of other electrodes can be defined relative to it i.e when an electrode has a standard potential of E, what that actually means is that it has a potential E relative to the hydrogen electrode.
