GCSE chemistry questions

If you’re looking to support a student as they prepare for their GCSE chemistry exams, our tutors can help. Every one of our dedicated tutors has experience helping students develop the skills and confidence they need to ace their exams.

Our GCSE chemistry tuition draws on our library of over 35,000 hours of bespoke content, ensuring that our tutors can create engaging and relevant sessions for every student’s unique needs.

Here are some sample GCSE chemistry questions from our library.

12 sample GCSE chemistry questions

1. Chemical cells produce a voltage. This voltage can be altered depending on what the electrodes are made from. Look at the electrochemical series and determine the best combination of electrodes to gain the highest voltage from the chemical cell.

    – Cobalt and iron
    – Nickel and chromium
    – Hydrogen and gold
    – Magnesium and copper

2. The empirical formula for an alkane is CnH2n+2 What is the empirical formula for an alkene?

3. What is the concentration of 0.1dm3 sulphuric acid, where it has neutralised 0.032dm3 of 0.8M sodium hydroxide? To two decimal places, how many moles are there in the sodium hydroxide?

4. Continuing from the above, account for the number of moles of sulphuric acid which react with the number of moles of sodium hydroxide. Answer to two decimal places.

5. Using the answers from the previous questions, what is the concentration of the sulphuric acid? Answer to one decimal place.

6. Select the correct anode half equation for copper chloride (CuCl₂).

8. True or false: energetics is the study of chemical changes caused by gravity

9. True or false: a calorimeter measures the amount of heat involved in a chemical reaction

10. True or false: enthalpy change means the amount of heat evolved, or absorbed, in a reaction carried out at constant pressure

11. True or false: if the enthalpy change is a negative number, it means the energy has been absorbed

    – Raise
    – Specific
    – Lower
