Question
- A. To purify a dissolved solid
- B. To separate a solid from a liquid
- C. To mix two liquids together
- D. To create a chemical reaction
Answer
The correct option is To purify a dissolved solid.
Explanation
The correct option is To purify a dissolved solid. To purify a dissolved solid is correct because it directly supports the approved learning objective to define a mixture as two or more elements or compounds that are not chemically combined. 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 74e627ed keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misunderstanding Mixtures
Students often define a mixture as a combination of elements or compounds that are chemically combined.
Remember that a mixture consists of two or more elements or compounds that are not chemically combined.
