alleryThe standard reduction potential of the standard hydrogen electrode (SHE) is assigned the value:
A$+1.00\,\text{V}$
B$+0.34\,\text{V}$
C$-1.00\,\text{V}$
D$0.00\,\text{V}$
Answer & Solution
Correct answer: D. $0.00\,\text{V}$
By convention, the standard hydrogen electrode (Pt electrode in contact with $1\,\text{M H}^+$ and $\mathrm{H_2}$ gas at $1\,\text{bar}$, $298\,\text{K}$) is assigned $E^\circ = 0.00\,\text{V}$.
All other standard electrode potentials are measured relative to this reference.
