Question
- A. To allow the flow of electricity through free-moving ions - correct ion focus for electrolysis
- B. Wrong ion focus: confuses electrolysis with a nearby Unit 4.4 chemical change idea
- C. Wrong particle check: uses the wrong ion, electrode, acid-base term, or product for The process of electrolysis
- D. Wrong reaction link: does not support Link electrolysis to decomposition of ionic compounds
Answer
The correct option is To allow the flow of electricity through free-moving ions - correct ion focus for electrolysis.
Explanation
The correct option is "To allow the flow of electricity through free-moving ions - correct ion focus for electrolysis" because it supports the approved learning objective: Link electrolysis to decomposition of 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 The process of electrolysis.
Common mistake
Confusing electrolysis with simple decomposition
Students think electrolysis is the same as a chemical decomposition reaction that occurs spontaneously, without the need for electricity or ion movement.
Explain that electrolysis is a specific type of decomposition that requires an external electric current to drive the separation of ions in a molten or aqueous ionic compound into their constituent elements at the electrodes.
