Question 1 · 1 mark · Difficulty 1/3

Which of the following is the correct word equation for the reaction between hydrochloric acid and sodium hydroxide?

  1. Hydrochloric acid + sodium hydroxide → sodium chloride + hydrogen
  2. Hydrochloric acid + sodium hydroxide → sodium chloride + water
  3. Hydrochloric acid + sodium hydroxide → sodium hydride + water
  4. Hydrochloric acid + sodium hydroxide → sodium chlorate + water
Show answer & explanation
✓ Answer: BHydrochloric acid + sodium hydroxide → sodium chloride + water
Award 1 mark for correct word equation showing neutralisation producing sodium chloride (salt) and water. A is incorrect — hydrogen gas is produced when acids react with metals, not bases. C is incorrect — sodium hydride is not a product of neutralisation. D is incorrect — sodium chlorate is a different compound formed under different conditions.
Question 2 · 1 mark · Difficulty 2/3

A farmer in St. Elizabeth, Jamaica, tested the soil in his field and found it had a pH of 4.5. He wants to grow callaloo, which grows best in soil with a pH between 6.0 and 7.0. Which substance should he add to the soil to make it suitable for callaloo?

  1. Sulphuric acid
  2. Slaked lime
  3. Ammonium sulphate
  4. Vinegar
Show answer & explanation
✓ Answer: BSlaked lime
Award 1 mark for identifying that slaked lime (calcium hydroxide) is a base that neutralises acidic soil to raise the pH. A is incorrect — sulphuric acid would make the soil more acidic. C is incorrect — ammonium sulphate is a fertiliser that can make soil more acidic. D is incorrect — vinegar is an acid and would lower the pH further.

CXC CSEC Integrated Science: Acids, Bases and Salts FAQ

How many CXC CSEC Integrated Science questions on Acids, Bases and Salts are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Acids, Bases and Salts for CXC CSEC Integrated Science, 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 CXC 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 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 Acids, Bases and Salts 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 Acids, Bases and Salts 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 Acids, Bases and Salts typically tested on CXC CSEC Integrated Science papers?
Acids, Bases and Salts 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.
