Chemical changes case 019 redox-boundary. A student explains a redox change. Which option uses the safest chemistry wording? Focus on Distinguish oxygen-transfer redox explanations from electron-transfer redox explanations in Oxidation and reduction in terms of electrons (HT only), not on a neighbouring Unit 4.4 reaction idea.
- A.Chemical changes case 019 redox-boundary: Links oxidation or reduction to the correct electron or oxygen change for Distinguish oxygen-transfer redox explanations from electron-transfer redox explanations
- B.Chemical changes case 019 redox-boundary: Uses reduction and displacement as if they mean the same thing (Oxidation and reduction in terms of electrons (HT only))
- C.Chemical changes case 019 redox-boundary: Calls the reaction redox without naming what changes (Distinguish oxygen-transfer redox explanations from electron-transfer redox explanations)
- D.Chemical changes case 019 redox-boundary: Confuses oxidation state with ionic charge in the answer (Reactivity of metals)
