Question

A. The ions are free to move. - correct ion focus for ion
B. Wrong ion focus: confuses ion 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 Explain why ions are discharged at electrodes during electrolysis

Answer

The correct option is The ions are free to move. - correct ion focus for ion.

Explanation

The correct option is "The ions are free to move. - correct ion focus for ion" because it supports the approved learning objective: Explain why ions are discharged at electrodes during electrolysis. 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

Misunderstanding Ion Discharge

Students often think that ions are discharged at electrodes simply because they are present in the electrolyte, without understanding the role of electron transfer.

Emphasize that ions are discharged at electrodes during electrolysis due to the gain or loss of electrons, which allows them to become neutral atoms or molecules.
