Question 1 · 1 mark · Difficulty 1/3

Which of the following is the correct definition of a base?

  1. A substance that turns universal indicator red
  2. A substance that produces hydrogen ions in aqueous solution
  3. A substance that neutralises an acid to form a salt and water only
  4. A substance with a pH greater than 7 when dissolved in water
Show answer & explanation
✓ Answer: CA substance that neutralises an acid to form a salt and water only
A base is defined as a substance that neutralises an acid to form a salt and water only. Option A describes an acid. Option C describes an acid (red on universal indicator). Option D describes an alkali specifically, which is a soluble base — not all bases dissolve in water, so this definition is incomplete.
Question 2 · 1 mark · Difficulty 1/3

A student adds a few drops of universal indicator to a solution and obtains a green colour. Which conclusion is correct?

  1. The solution is neutral with pH 7
  2. The solution is strongly alkaline with pH 10
  3. The solution is a strong acid with pH 4
  4. The solution is a weak alkali with pH 8
Show answer & explanation
✓ Answer: AThe solution is neutral with pH 7
Universal indicator turns green at pH 7, which corresponds to a neutral solution. A strong acid (pH 4) would give a red/orange colour. A strongly alkaline solution (pH 10) would give a dark blue or purple colour. A weak alkali (pH 8) would give a blue-green colour, not the definitive green of neutrality.

CIE IGCSE Chemistry: Acids, bases and salts: definitions and reactions FAQ

How many CIE IGCSE Chemistry questions on Acids, bases and salts: definitions and reactions are there on Kramizo?
Kramizo currently has 40 exam-board-aligned practice questions on Acids, bases and salts: definitions and reactions 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 Acids, bases and salts: definitions and reactions 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 Acids, bases and salts: definitions and reactions 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 Acids, bases and salts: definitions and reactions typically tested on CIE IGCSE Chemistry papers?
Acids, bases and salts: definitions and reactions 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.
