For The process of electrolysis, which electrolysis focus answer best supports this Unit 4.4 objective: Explain why ions are discharged at electrodes during electrolysis?

The correct option is The ionic compound must be molten or dissolved in water. - correct electrolysis focus for ion.

The correct option is The ionic compound must be molten or dissolved in water. - correct electrolysis focus for ion. The ionic compound must be molten or dissolved in water. - correct electrolysis focus for ion is correct because it directly supports the approved learning objective to explain why ions are discharged at electrodes during electrolysis. This electrolysis focus variant asks students to separate ion from similar Unit 4.4 chemical-change ideas. The reasoning belongs to The process of electrolysis within Electrolysis, so it should not be confused with nearby ideas about acids, alkalis, bases, oxidation, reduction, displacement, reactivity, electrolysis, electrodes, ions, pH, or salt preparation unless those are named in the objective. Use the focus term ion to keep the answer aligned with AQA GCSE Chemistry 8462 Unit 4.4 Chemical changes. Keep acid, alkali and base distinct; keep oxidation and reduction distinct; do not mix reduction with displacement; keep electrolysis separate from electroplating; distinguish anode from cathode, positive ions from negative ions, oxidation state from ionic charge, and strong acid from concentrated acid. The other options are weaker because they either use the wrong reaction type, wrong ion, wrong electrode, wrong acid-base distinction, vague wording, or the wrong chemical-change context.
