Question 1 · 1 mark · Difficulty 1/3

What is meant by the term electrolyte in the electrolysis required practical?

  1. An ionic substance, molten or dissolved in water, that conducts electricity and is broken down
  2. An insulating solid that stops current flowing through the cell
  3. The gas collected in a small tube held over an electrode
  4. The metal wire that carries electrons back to the power supply
Show answer & explanation
✓ Answer: AAn ionic substance, molten or dissolved in water, that conducts electricity and is broken down
Award 1 mark. The ions must be free to move before any current can pass, which is why the compound is melted or dissolved. The wires carry electrons, but only the electrolyte is decomposed.
Question 2 · 1 mark · Difficulty 1/3

Which material is normally used for the inert electrodes in this required practical?

  1. Graphite
  2. Iron
  3. Zinc
  4. Sodium
Show answer & explanation
✓ Answer: AGraphite
Award 1 mark. Graphite conducts because of its delocalised electrons but does not react with the electrolyte or the products, so the observations come from the electrolyte alone. Sodium, iron and zinc would all take part in reactions.

AQA GCSE Chemistry: Required practical: electrolysis FAQ

Is Kramizo free for AQA GCSE students preparing for Chemistry?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Required practical: electrolysis practice with other Chemistry topics or even switch to a totally different AQA subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Required practical: electrolysis 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 Required practical: electrolysis typically tested on AQA GCSE Chemistry papers?
Required practical: electrolysis 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. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
