Question
- A. They are gained by the zinc ion - correct redox focus for HT only
- B. Wrong redox focus: confuses HT only with a nearby Unit 4.4 chemical change idea
- C. Wrong particle check: uses the wrong ion, electrode, acid-base term, or product for Oxidation and reduction in terms of electrons (HT only)
- D. Wrong reaction link: does not support (HT only) Define reduction as gain of electrons
Answer
The correct option is They are gained by the zinc ion - correct redox focus for HT only.
Explanation
The correct option is "They are gained by the zinc ion - correct redox focus for HT only" because it supports the approved learning objective: (HT only) Define reduction as gain of electrons. The other options are incorrect or weaker because they are vague, use the wrong Chemistry context, or do not clearly explain the answer for Oxidation and reduction in terms of electrons (HT only).
Common mistake
Misunderstanding Reduction
Students often confuse reduction with the addition of oxygen instead of the gain of electrons.
Remember that reduction specifically refers to the gain of electrons, while oxidation is the loss of electrons.
