Show answer & explanation
✓ Answer: AFat + sodium hydroxide → soap + glycerol
Award 1 mark for correct identification of saponification products. D is incorrect — this describes hydrolysis, not saponification, and produces fatty acids rather than soap. B is incorrect — saponification requires a strong alkali, not an acid. C is incorrect — sodium chloride is a neutral salt and cannot cause saponification.

WJEC GCSE Chemistry: Organic Chemistry FAQ

Is Kramizo free for WJEC 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 Organic Chemistry practice with other Chemistry topics or even switch to a totally different WJEC 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 Organic Chemistry questions aligned to the official WJEC GCSE Chemistry syllabus?
Every question is written against the published WJEC 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 WJEC 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 WJEC.
How is Organic Chemistry typically tested on WJEC GCSE Chemistry papers?
Organic Chemistry appears across multiple question types on real WJEC 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.
