Short explanation

(HT only) Distinguish oxygen-transfer redox explanations from electron-transfer redox explanations. This objective belongs to Oxidation and reduction in terms of electrons (HT only) within Reactivity of metals for AQA GCSE Chemistry 8462. A strong answer should use HT only accurately, explain the chemistry behind the statement, and connect the idea back to the exact command in the objective. When revising, separate this point from neighbouring Chemistry ideas by naming the relevant particle, substance, process, calculation, observation, or structure before giving the final conclusion.
