Question 1 · 1 mark · Difficulty 1/3

A student in Barbados prepared copper(II) sulfate crystals by adding excess copper(II) oxide to dilute sulfuric acid. Which method should be used to remove the unreacted copper(II) oxide from the solution?

  1. Evaporation
  2. Filtration
  3. Crystallisation
  4. Distillation
Show answer & explanation
✓ Answer: BFiltration
Award 1 mark for B. Filtration separates the unreacted solid copper(II) oxide from the soluble copper(II) sulfate solution. A is incorrect because evaporation would concentrate the solution but not remove the solid. C is incorrect because crystallisation is used after filtration to obtain crystals from the solution. D is incorrect because distillation separates liquids or removes solvent, not insoluble solids.
Question 2 · 1 mark · Difficulty 2/3

Which salt would produce a white precipitate when a solution of it is mixed with dilute hydrochloric acid?

  1. Sodium sulfate
  2. Calcium nitrate
  3. Silver nitrate
  4. Potassium chloride
Show answer & explanation
✓ Answer: CSilver nitrate
Award 1 mark for C. Silver nitrate reacts with hydrochloric acid (or any chloride) to form silver chloride, which is a white precipitate: AgNO₃ + HCl → AgCl + HNO₃. A is incorrect because sodium sulfate and hydrochloric acid produce soluble products. B is incorrect because calcium nitrate and hydrochloric acid produce soluble products. D is incorrect because both ions are already present as potassium chloride is soluble.

Are the Preparation and Properties of Salts questions aligned to the official CXC CSEC Chemistry syllabus?
Every question is written against the published CXC CSEC Chemistry 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 Preparation and Properties of Salts typically tested on CXC CSEC Chemistry papers?
Preparation and Properties of Salts appears across multiple question types on real CXC CSEC 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.
