Standard electrode potential of standard hydrogen electrode (SHE) is:
A-1 V
B0.5 V
C0 V (by convention, reference)
D+1 V
Answer & Solution
Correct answer: C. 0 V (by convention, reference)
SHE: 2H⁺(1 M) + 2e⁻ → H₂(1 atm) is assigned E° = 0 V by convention. All other standard reduction potentials measured relative to SHE.
