- The key ideas to know are half equation.
- 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 Redox equations to exam-style questions, flashcards, and revision notes for Oxidation, reduction and redox equations.
Quick student answer
Which of the following half-equations represents the reduction of copper(II) ions?
Direct answer
Cu^2+ + 2e^- → Cu
Key terms
- Redox Reaction: A chemical reaction involving the transfer of electrons between two species, resulting in oxidation and reduction.
- Oxidation State: A number that represents the total number of electrons that an atom either gains or loses to form a chemical bond.
Common trap
Confusing Oxidation and Reduction: Remember that oxidation involves an increase in oxidation state, while reduction involves a decrease.
