True or False: The standard hydrogen electrode (SHE) has a potential of 0 V by definition.
- True
- False
Answer: True
SHE is the reference electrode with E° = 0.00 V at 298K, 1 atm, 1M H⁺. All other electrode potentials are measured relative to SHE. Fundamental for electrochemical series. [[NCERT Chemistry Class 12]]
