Question
- A. Aluminium at the cathode, oxygen at the anode - correct electrolysis focus for molten ionic compound
- B. Wrong electrolysis focus: confuses molten ionic compound with a nearby Unit 4.4 chemical change idea
- C. Wrong particle check: uses the wrong ion, electrode, acid-base term, or product for Electrolysis of molten ionic compounds
- D. Wrong reaction link: does not support Write word equations for electrolysis of molten ionic compounds
Answer
The correct option is Aluminium at the cathode, oxygen at the anode - correct electrolysis focus for molten ionic compound.
Explanation
The correct option is "Aluminium at the cathode, oxygen at the anode - correct electrolysis focus for molten ionic compound" because it supports the approved learning objective: Write word equations for electrolysis of molten ionic compounds. The other options are incorrect or weaker because they are vague, use the wrong Chemistry context, or do not clearly explain the answer for Electrolysis of molten ionic compounds.
Common mistake
Common Mistake in Writing Word Equations
Students often forget to include the states of the reactants and products in their word equations for electrolysis.
Always specify the physical states of the substances (e.g., solid, liquid, gas) when writing word equations to provide a complete representation of the reaction.
