Voltaic Cell: Standard Hydrogen Electrode Computer Animation

 A Standard Hydrogen Electrode (SHE) is used to show the E°cell generated in order to determine the standard reduction potentials of two half-reactions: Zn2++ 2e- -> Zn and  Cu2++ 2e- -> Cu for SHE||Cu2+|Cu and Zn|Zn2+||SHE electrochemical cells.  A H2(g) tank serves as the source of H2(g) being bubbled into the SHE in1.00 M HCl(aq) at 25°C ,1.00 atm pressure, near sea level.
