Question 2 · 1 mark · Difficulty 1/3

Alloys such as brass are described as formulations because they are:

  1. produced by a chemical reaction between two metals
  2. compounds with one fixed chemical formula
  3. single pure elements
  4. mixtures of metals combined in carefully controlled proportions

Are the Chemical analysis: purity and formulations questions aligned to the official AQA GCSE Chemistry syllabus?
Every question is written against the published AQA GCSE Chemistry specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real AQA paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from AQA.
How is Chemical analysis: purity and formulations typically tested on AQA GCSE Chemistry papers?
Chemical analysis: purity and formulations appears across multiple question types on real AQA GCSE Chemistry papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response.
