Question
- A. They lose electrons - correct redox focus for electrode
- B. Wrong redox focus: confuses electrode 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 Explain electrode products using movement and discharge of ions
Answer
The correct option is They lose electrons - correct redox focus for electrode.
Explanation
The correct option is "They lose electrons - correct redox focus for electrode" because it supports the approved learning objective: Explain electrode products using movement and discharge of ions. 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
Misunderstanding Ion Movement
Students often confuse the movement of ions during electrolysis, thinking that positive ions move to the anode instead of the cathode.
Remember that positive ions are attracted to the negative electrode (cathode) where they gain electrons, while negative ions move to the positive electrode (anode) to lose electrons.
