Quick explanation
Predict the feasibility of redox reactions using electrode potentials
- This point belongs to Electrode potentials and electrochemical cells (A-level only), especially Feasibility and applications of cells (A-level only).
- You need to be able to predict the feasibility of redox reactions using electrode potentials.
- The key ideas to know are electrode potential.
- 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 Feasibility and applications of cells (A-level only) to exam-style questions, flashcards, and revision notes for Electrode potentials and electrochemical cells (A-level only).
Quick student answer
Which of the following statements about standard electrode potentials is true?
Direct answer
All of the above.
Key terms
- Standard Electrode Potential (E°): The measure of the tendency of a chemical species to be reduced, measured under standard conditions.
- Galvanic Cell: An electrochemical cell that derives electrical energy from spontaneous redox reactions occurring within the cell.
Common trap
Incorrectly identifying the anode and cathode: Remember that the anode is where oxidation occurs (loss of electrons) and the cathode is where reduction occurs (gain of electrons).
