For Representation of reactions at electrodes as half equations (HT only), which acid-base focus answer best supports this Unit 4.4 objective: (HT only) Explain that oxidation happens at the anode because negative ions lose electrons?.
- A.Negative ions lose electrons at the anode - correct acid-base focus for HT only
- B.Wrong acid-base focus: confuses HT only with a nearby Unit 4.4 chemical change idea
- C.Wrong particle check: uses the wrong ion, electrode, acid-base term, or product for Representation of reactions at electrodes as half equations (HT only)
- D.Wrong reaction link: does not support (HT only) Explain that oxidation happens at the anode because negative ions lose electrons
