Question 1 · 1 mark · Difficulty 1/3

A student in Trinidad wants to obtain pure water from a sample of sea water collected at Maracas Bay. Which technique would be MOST suitable?

  1. Filtration
  2. Simple distillation
  3. Decantation
  4. Evaporation
Show answer & explanation
✓ Answer: BSimple distillation
Award 1 mark for recognising that distillation allows collection of pure water by evaporating and condensing it, leaving dissolved salts behind. D is incorrect — evaporation would leave the water to escape and only collect the salt. A is incorrect — filtration cannot separate dissolved substances. C is incorrect — decantation separates immiscible liquids or settles solids, not dissolved salts.
Question 2 · 1 mark · Difficulty 1/3

Which of the following represents a compound?

  1. N₂
  2. O₂
  3. NaCl
  4. Cu
Show answer & explanation
✓ Answer: CNaCl
Award 1 mark for NaCl (sodium chloride). NaCl contains two different elements (sodium and chlorine) chemically combined. B is incorrect — O₂ is an element (contains only oxygen atoms). D is incorrect — Cu is the symbol for the element copper. A is incorrect — N₂ is an element (contains only nitrogen atoms).

CXC CSEC Integrated Science: Matter and Separation Techniques FAQ

Is Kramizo free for CXC CSEC students preparing for Integrated Science?
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 Matter and Separation Techniques practice with other Integrated Science topics or even switch to a totally different CXC 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 Matter and Separation Techniques questions aligned to the official CXC CSEC Integrated Science syllabus?
Every question is written against the published CXC CSEC Integrated Science specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC 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 CXC.
How is Matter and Separation Techniques typically tested on CXC CSEC Integrated Science papers?
Matter and Separation Techniques appears across multiple question types on real CXC CSEC Integrated Science 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.
