For Electrolysis of aqueous solutions, which exam wording answer best supports this Unit 4.4 objective: Make and test predictions about products formed during electrolysis of aqueous solutions. (WS 2.2)?

The correct option is The process of splitting an ionic compound using electricity - correct exam wording for WS 2.2.

The correct option is The process of splitting an ionic compound using electricity - correct exam wording for WS 2.2. The process of splitting an ionic compound using electricity - correct exam wording for WS 2.2 is correct because it directly supports the approved learning objective to make and test predictions about products formed during electrolysis of aqueous solutions. (WS 2.2). This exam wording variant asks students to separate WS 2.2 from similar Unit 4.4 chemical-change ideas. The reasoning belongs to Electrolysis of aqueous solutions 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 WS 2.2 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.
