Question
- A. The halogen replaces the halide ion in the compound
- B. The halide ion replaces the halogen in the compound
- C. No reaction occurs between the halogen and halide salt
- D. The halogen and halide salt form a new compound
Answer
The correct option is The halogen replaces the halide ion in the compound.
Explanation
The correct option is The halogen replaces the halide ion in the compound. The halogen replaces the halide ion in the compound is correct because it directly supports the approved learning objective to explain displacement reactions between halogens and halide salts. This is tested in the subtopic Group 7 within The periodic table, so the reasoning must stay within AQA GCSE Chemistry 8462 Unit 4.1. The other options are weaker because they either confuse a nearby Chemistry concept, use the wrong subtopic context, or do not answer Group 7 precisely. Repair marker 79a6b2fd keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misunderstanding Displacement Reactions
Students often think that halogens can displace any halide salt regardless of their reactivity.
Remember that a more reactive halogen can displace a less reactive halide from its salt, while a less reactive halogen cannot displace a more reactive one.
