Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. 1.00 V
  2. 0.00 V
  3. -1.00 V
  4. 2.40 V

Correct answer and explanation

Correct answer: 0.00 V

Explanation: āœ… Correct Answer: B) 0.00 V šŸ“š Explanation: The Standard Hydrogen Electrode (SHE) is the universal reference electrode used in electrochemistry. By international scientific convention, the standard electrode potential of the SHE is arbitrarily assigned an exact value of 0.00 Volts at all temperatures. All other standard reduction potentials are measured relative to this baseline.
