Key terms

  • anode: The positive electrode where oxidation occurs during electrolysis. In Using electrolysis to extract metals, this term helps explain describe oxide ions losing electrons at the anode to form oxygen for AQA GCSE Chemistry 8462 Unit 4.4.
  • oxide ion: A negatively charged ion formed when oxygen gains electrons. In Using electrolysis to extract metals, this term helps explain describe oxide ions losing electrons at the anode to form oxygen for AQA GCSE Chemistry 8462 Unit 4.4.

Common trap

Confusing Oxide Ion Behavior: Remember that oxidation occurs at the anode, where negative ions like oxide lose electrons to form oxygen.
