Question 1 · 1 mark · Difficulty 1/3

A student separates a mixture of food colourings using paper chromatography. Which property of the colourings allows them to be separated?

  1. Their different solubilities in the solvent
  2. Their different densities
  3. Their different melting points
  4. Their different electrical conductivities
Show answer & explanation
✓ Answer: ATheir different solubilities in the solvent
Award 1 mark for identifying that chromatography separates substances based on their different solubilities in the mobile phase (solvent). B is incorrect because density differences are not the basis of chromatography separation. C is incorrect because melting points are not relevant to chromatography. D is incorrect because electrical conductivity is not used in paper chromatography.
Question 2 · 1 mark · Difficulty 2/3

A forensic scientist uses thin layer chromatography to analyse ink from a suspected forged document. She measures that a component has moved 4.5 cm from the baseline and the solvent front has moved 6.0 cm. What is the Rf value of this component?

  1. 0.75
  2. 1.33
  3. 10.5
  4. 27.0
Show answer & explanation
✓ Answer: A0.75
75. Award 1 mark for correct calculation. Rf = distance moved by component ÷ distance moved by solvent front = 4.5 ÷ 6.0 = 0.75. B is incorrect because it inverts the calculation (6.0 ÷ 4.5). C is incorrect because it adds the distances instead of dividing. D is incorrect because it multiplies the distances.

CIE IGCSE Chemistry: Experimental Techniques and Chemical Analysis FAQ

How many CIE IGCSE Chemistry questions on Experimental Techniques and Chemical Analysis are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Experimental Techniques and Chemical Analysis for CIE IGCSE Chemistry, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CIE paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CIE IGCSE 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 Experimental Techniques and Chemical Analysis practice with other Chemistry topics or even switch to a totally different CIE 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 Experimental Techniques and Chemical Analysis questions aligned to the official CIE IGCSE Chemistry syllabus?
Every question is written against the published CIE IGCSE Chemistry specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CIE 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 CIE.
How is Experimental Techniques and Chemical Analysis typically tested on CIE IGCSE Chemistry papers?
Experimental Techniques and Chemical Analysis appears across multiple question types on real CIE IGCSE 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.
