Q: Is Kramizo really free for AQA Chemistry students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Chemistry questions aligned to the AQA GCSE syllabus?

Every question is written against the published AQA GCSE Chemistry syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real AQA past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

Iron(III) chloride has the formula FeCl₃. What is the oxidation state of iron in this compound?

Accepted Answer

C: +3 — Each chloride ion carries a charge of −1. In FeCl₃, there are three chloride ions, giving a total of −3. For the compound to be electrically neutral, the iron must have an oxidation state of +3. This is why it is named iron(III) chloride, where the Roman numeral indicates the oxidation state.
