The reduction potential for all other half-reactions are measured relative to the half-reaction

2H+(aq) + 2e- −> H2​(g)

Under standard conditions (pH=0.000, PH2 = 1 atm) this standard hydrogen electrode (SHE) is defined to have a reduction potential of 0.000 V.

What is the reduction potential of a hydrogen electrode that is still at standard pressure, but has pH = 6.25 , relative to the SHE?
