Practical questions

You will complete eight required core practical activities if you are studying GCSE Chemistry, and 18 if you are studying GCSE Combined Science (five of these are in Chemistry).

You could be asked questions about the apparatus, methods, safety precautions, results, analysis and evaluation of these experiments.

There are no core practical activities in the Key concepts in Chemistry section.

These questions have been written by Bitesize consultants as suggestions to the types of questions that may appear in an exam paper.

Sample question 1 - Foundation

Question

Name one piece of apparatus suitable for measuring different volumes of liquids. [1 mark]

  • Measuring cylinder/burette/graduated pipette. [1]

Sample question 2 - Foundation

Question

Give two reasons why hazard symbols are used on containers in the laboratory. [2 marks]

  • To indicate the dangers associated with the contents. [1]
  • To inform people about safe-working precautions with these substances in the laboratory. [1]

Sample question 3 - Higher

Question

Describe the difference between a hazard and a risk. [2 marks]

  • A hazard is something that could cause damage or harm to someone or something. [1]
  • A risk is the chance that a hazard will cause damage or harm. [1]

Sample question 4 - Higher

Question

A student carries out an experiment to determine the empirical formula of magnesium oxide. The student heats magnesium in a crucible strongly for five minutes.

Explain a safety precaution the student should take to reduce the risk of harm in this experiment. [2 marks]

  • Allow the crucible to cool before moving it/use tongs. [1]
  • The crucible will be become very hot during heating and could cause burns. [1]
