Understanding SHE

Postby GFolk_1D » Tue Mar 03, 2020 1:45 pm

Hi! I understand that standard cell potentials are based upon references to the SHE model but could some one further explain what exactly the SHE entails?

SHE is the standard hydrogen electrode. It uses a platinum electrode. It is used as a reference and its cell potential is 0V. It is useful since it can take the place of either the cathode or the anode in order for the reaction to be spontaneous.

E must be found by comparing an anode and a cathode, so you would use the SHE as the comparative E when finding other reactions E since E=0 for SHE.
