alleryThe standard hydrogen electrode (SHE) is assigned a standard electrode potential of:
A0.00 V (by convention)
B+1.00 V
C+0.76 V
D−0.34 V
Answer & Solution
Correct answer: A. 0.00 V (by convention)
SHE — Pt(s) | H₂(g, 1 bar) | H⁺(aq, 1 M) — is assigned **E° = 0.00 V at all temperatures**, serving as the reference for all other standard electrode potentials.
