Quick explanation
Describe the standard hydrogen electrode
- This point belongs to Electrode potentials and electrochemical cells (A-level only), especially Standard electrode potentials (A-level only).
- You need to be able to describe the standard hydrogen electrode.
- The key ideas to know are standard hydrogen electrode.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Standard electrode potentials (A-level only) to exam-style questions, flashcards, and revision notes for Electrode potentials and electrochemical cells (A-level only).
Quick student answer
What is the standard electrode potential of the standard hydrogen electrode (SHE)?
Direct answer
The standard electrode potential of the standard hydrogen electrode is defined as 0.00 V.
Key terms
- Standard Electrode Potential: The measure of the tendency of a chemical species to be reduced, measured under standard conditions.
- Standard Hydrogen Electrode (SHE): A reference electrode with a potential of 0.00 V, used to measure the electrode potentials of other half-cells.
Common trap
Confusing electrode potentials: Remember that the SHE is defined as 0.00 V and serves as a reference point for all other measurements.
