Question
- A. To separate a liquid from a solution based on boiling point
- B. To separate a solid from a liquid based on particle size
- C. To separate different liquids based on their densities
- D. To separate gases from liquids based on solubility
Answer
The correct option is To separate a liquid from a solution based on boiling point.
Explanation
The correct option is To separate a liquid from a solution based on boiling point. To separate a liquid from a solution based on boiling point is correct because it directly supports the approved learning objective to describe simple distillation and fractional distillation as separation techniques for liquids and solutions. This is tested in the subtopic Mixtures within A simple model of the atom, symbols, relative atomic mass, electronic charge and isotopes, 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 Mixtures precisely. Repair marker 55ab9379 keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Confusing Distillation Techniques
Students often confuse simple distillation with fractional distillation, thinking they are the same process.
Remember that simple distillation is used for separating liquids with significantly different boiling points, while fractional distillation is used for separating mixtures of liquids with closer boiling points. Keep the correction anchored to Mixtures and avoid mixing it with nearby Unit 4.1 ideas.
