Quick explanation
Explain limitations of predictions based on standard conditions
- 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 explain limitations of predictions based on standard conditions.
- The key ideas to know are based, conditions, and predictions.
- 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
A higher standard electrode potential indicates a stronger oxidizing agent.
Key terms
- Oxidizing Agent: A substance that gains electrons in a redox reaction and is reduced.
- Reducing Agent: A substance that loses electrons in a redox reaction and is oxidized.
Common trap
Confusing Oxidation and Reduction: Remember that oxidation involves loss of electrons and reduction involves gain of electrons. Use the mnemonic 'OIL RIG' (Oxidation Is Loss, Reduction Is Gain).
