Standard electrode potential of SHE (Standard Hydrogen Electrode) is taken as:
A0 V
BVariable
C-1.0 V
D+1.0 V
Answer & Solution
Correct answer: A. 0 V
SHE is defined as the reference: E°(SHE) = 0 V by convention. All other electrode potentials are measured relative to it. 2H+ (1 M) + 2e- → H2 (1 atm) at 25°C, with Pt electrode.
