Question
- A. Separating mixtures
- B. Measuring temperature
- C. Calculating mass
- D. Creating compounds
Answer
The correct option is Separating mixtures.
Explanation
The correct option is Separating mixtures. Separating mixtures is correct because it directly supports the approved learning objective to describe chromatography as a separation technique for mixtures. 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 852c1973 keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misunderstanding Chromatography
Students often think that chromatography can separate any type of mixture, including those that are not soluble in the chosen solvent.
Emphasize that chromatography is effective only for mixtures where the components are soluble in the solvent used.
