Question

A. A technique used to separate liquids with different boiling points
B. A method to separate solids from liquids
C. A process to purify gases
D. A way to mix two liquids thoroughly

Answer

The correct option is A technique used to separate liquids with different boiling points.

Explanation

The correct option is A technique used to separate liquids with different boiling points. A technique used to separate liquids with different boiling points 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 74604c2f 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.
